Keeping it: checking, cleaning, rotating, storing and recording
A framed picture is a thing with a maintenance interval. This chapter sets a yearly check, limits cleaning to what conservation bodies allow, rotates sensitive pieces against an exposure budget, and builds a record an insurer or an appraiser could read.
Start here Essentials
At minimum this chapter asks you to put one date a year in a calendar and write one record per piece. Everything marked Go deeper is optional on a first pass.
- Put one date a year in your calendar. On it, check every hanging and every frame back (The yearly check).
- Dust the outside of the glazing only. Use nothing on the forbidden list (Cleaning).
- Photograph each piece and write its row in the picture list. One row per piece is enough (Your pictures).
- For any sensitive piece, work out its rotation date. The exposure calculator gives it (the rotation box).
Minimum time: about 20 minutes a year for a houseful, plus an hour once to set up the records. Done when: every piece has a photograph and a record, every hanging has been checked once, and each sensitive piece has a date to come down.
1. The yearly check Understand
Framed pictures are the one category of household object nobody services. They hang there for twenty years and are noticed again when something has gone wrong.
The published interval is longer than ours. The UK trade specification suggests frames are ideally inspected every five years, and asks for a label on the back saying so. A practitioner guide prepared with a museum packing and handling network says all hanging methods should be re-checked annually. We suggest a year, which is our interval and not a published one, on the grounds that it takes twenty minutes and that the hardware half of the check is where the annual advice already is.
What to look at, grouped as the care log's checklist groups it:
| Part | What you are looking for | Why it matters |
|---|---|---|
| The hanging | Hook or anchor still tight; nothing has shifted; wire, D-rings or strap hangers sound with no kinks or rust; the piece still level; pads at the lower corners still there | Hardware is the failure that takes the picture with it, and the margin rule's own source asks for annual re-checking |
| The package | Glazing not cracked, chipped or loose in the rabbet; dust cover and any taped join intact; nothing inside has moved against the glazing | A conservation institute asks that chipped, broken or brittle glass be replaced, and contact with glazing is the one thing every publisher warns about |
| The piece | Looked at through the glazing for fading, cockling, new spots; no musty smell at the back | Fading is slow enough that only a comparison over years catches it, which is what the record is for. A musty smell is often the first sign of mold |
| The records | Picture file exported; photographs still somewhere you could find them | Browser storage is convenient and fragile, and a record you cannot find is not a record |
Write what you found, including "nothing", in the findings sheet. A row that says "checked, nothing" in three consecutive years is what makes the fourth year's "the wire looks kinked" mean something.
2. Cleaning, and the published list of what never to use
The strongest published prohibitions in this whole subject are about cleaning, and they come from a conservation institute's note on cleaning paintings. The list, in its own terms: do not use dry or moist dust cloths, stiff bristle brushes or feather dusters on the surface of a painting; do not use a vacuum to remove dust from a painting surface or from the surface of its frame; do not use compressed canned air; and do not use commercial paint cleaners or picture restoring preparations, which it says are neither used nor recommended by professional paintings conservators. Physical principle
The reason is in the same note and it is worth knowing, because it explains why careful dusting is not safer than no dusting: tiny partially detached paint flakes are not immediately visible and can be swept away by even the lightest dusting. Threads catch on impasto. Moisture causes paint loss. Bristles and feathers scratch.
So the household version is narrow and it is this:
- Clean the outside of the glazing, and nothing else. The same institute says to clean the glazing with a lightly dampened cloth, taking care not to touch the frame nor to allow liquid to run between the frame and the glazing.
- Do not spray anything at a framed picture. Liquid runs down behind the glazing and into the package. Dampen the cloth, away from the picture.
- Acrylic glazing follows its own product's instructions. A professional wiki says solvent-containing cleaners cause microcracks on acrylic; one maker of a coated acrylic says to use common household glass cleaners and not acrylic cleaners or polishing agents. Coatings differ. Where you do not know, use a dry soft cloth. Product-specific
- The frame gets a soft brush, dry. The institute notes that dusting an ornate frame can scratch its often fragile surface finish, and that wet-wiping will remove surface finishes, especially traditional gilding. A state archives suggests a magnetic cloth or a soft brush.
- Unframed work is handled with both hands, and with gloves for paintings. The institute's note says to always wear gloves when handling unframed paintings, because natural oils from fingers etch into unprotected paint layers and leave indelible marks.
And the restatement that belongs here rather than in the framing chapters, because it is a thing to check rather than a thing to specify: a conservation institute asks for a minimum space of half a centimetre between the highest point of a painting and the glazing. If you can see the surface touching the glass, that is a reframing job.
3. Rotation
Light damage is cumulative and irreversible, and a preservation leaflet draws the conclusion in one sentence: no paper, wood, leather, textile or other organic object should be on permanent display. A national library says long-term or permanent display of paper-based materials is not recommended.
That does not mean leaving walls bare. It means a sensitive piece comes down for a while, and the interval is arithmetic rather than judgment: an annual exposure budget divided by what your wall actually delivers. The rotation box does it, taking the published duration table, your measured level and a start date, and returning the date to take the piece down.
What goes back up in the meantime is the interesting question, and the conservation answer is the one households are rarely offered: a good copy. A national library's framing guidance says the preferred alternative to long-term display is to store the original well and frame a well-made reproduction. The national archives says the same to families and adds the practical note that color scans or color photocopies can make good quality copies for display, with its own photograph of two drawings where the marker faded except where one overlapped the other. Learn Digital Photo Care's chapter on prints, slides and negatives covers getting a good scan made.
Write the rotation date in the rotation sheet with the piece, the level you measured, the yearly exposure and what goes up instead. A date with nothing to replace it is a date that gets ignored.
4. When something is wrong
Four situations have published first-aid, and in each the useful part is where the line falls between what you do and what a conservator does.
Something splashed it. A conservation institute's protocol: if liquids splash against a painted surface, immediately place the painting face up to avoid running drips, do not rub the painting to remove the liquid, but wick it up using the corner of an absorbent paper or cloth, and call in an expert. Face up, wick rather than rub, then stop.
Water or a flood reached it. The national archives publishes household guidance, and the framed-item rule is the one to memorize: remove the backing material from the frame; if the item is not stuck to the glass, carefully remove it and air dry; if it appears stuck to the glass, do not attempt to remove it, and dry it intact with the glass side down. Its other rules: air dry with fans positioned so air does not blow directly onto the materials; do not attempt to remove active mold, because it may spread or smear; freeze items that cannot be dried within two days; and never freeze old photographs or negatives, which are air dried individually, face up.
Mold. A federal leaflet's prevention figures are in The walls to avoid. For an outbreak, three facts from the same leaflet matter. Extreme cold, freezing and heat deactivate spores or spore growth but do not kill them, and if temperatures rise after cold, spores can be reactivated. Killing mold does not eliminate all health hazards, because inactive mold may cause allergic reactions. And often the first indication of a problem is a characteristic musty odor. Its protective equipment list for handling infested material is a HEPA respirator, goggles, disposable gloves and a washable coat.
It fell, or the glazing cracked. Treat the glass as the hazard first: gloves, tape across the break before moving it, wrap the pieces, and go over the floor twice before letting children or pets back in. Then photograph everything before you move the piece, because that photograph is what an insurer and a conservator both want. A conservation institute's condition reporting note lists the occasion explicitly: a report is made immediately after damage occurs, stating the nature, cause, time and location of the incident.
And the line, in every case. A conservation institute says do not attempt to remove even a minor blemish from a painting, and that commercial picture restoring preparations are neither used nor recommended by professional paintings conservators. The national archives says items of high monetary, historic or sentimental value should be treated in consultation with a conservator, and that a professional conservation body maintains a referral list. That is the referral path: the professional body's find-a-conservator service, which a federal agency and a museum conservator both point households to.
Everything in this chapter stops at the surface of the glazing. This manual does not clean, flatten, unstick, repair or treat anything, and it does not value anything. It names the signs, gives the first-aid steps that are published, and says who takes it from there. The insurance section lists what to ask and does your own arithmetic; it is not insurance advice, and nothing here is a valuation.
5. Storing
Unframed work on paper goes flat and dark. A conservation institute's note is specific: acid-free materials only, with both neutral-pH and alkaline-buffered products acceptable for most works on paper; before storage, dust with a soft brush and remove foreign materials that are not part of the artifact, including plastic envelopes, newspapers, acidic wrapping papers, cardboard mats or backings, dried adhesive tapes and metal fasteners such as paper clips; and keep works on poor-quality paper separate from those on good-quality paper to avoid transferring acids. It gives a maximum acceptable temperature of 21 degrees Celsius and notes that relative humidity over 60 percent accelerates chemical and biological deterioration and promotes distortion of paper.
The same note has the tip that links storage to framing: where a collection consists of numerous works, storing them in mats cut to standard sizes allows the use of standard-sized frames for exhibition. Mat once, rotate freely.
Framed work leaning against a wall is not a storage strategy, and a conservation institute says so in those terms. If it must happen temporarily, its figures are: paintings supported at least 7 to 10 cm above the floor to protect them from dirt, dust and possible contact with water; no more than four to five stacked together; rigid separator boards between each artwork, slightly larger than the works they sit against; largest against the wall and working down to the smallest; the outermost one facing inward toward a separator; and ornate frames stacked face outward, away from the wall, so as little weight as possible rests on fragile ornamentation.
Its siting rules are the same as the hanging ones: avoid attics and basements, because attics experience extremes of heat and dryness and basements can be damp and vulnerable to flooding; avoid perimeter walls, which can fluctuate and can be a source of moisture; and do not place storage in areas subject to vibration. It adds that before paintings enter storage it is preferable to fit them with frames and protective backing boards, and that vertical storage for framed paintings is suitable only for objects in stable condition.
A storage screen is the proper answer for more than a few framed pieces, and a federal museum leaflet publishes a buildable one: two-inch square vertical supports no more than ten feet long, lag-bolted to studs at 16 to 24 inch centers through quarter-inch clearance holes about 18 inches apart, with vinyl-coated steel garden fencing stretched across at one-foot intervals and paintings hung on it with S-hooks, aisles at least three feet wide, heavier objects on the lower portion of a panel. It is a garage or spare-room project, not a museum one.
6. Moving
Two published procedures cover most of what a household needs.
Wrapping a framed picture. A conservation institute's note explains the principle first: a well-sealed wrapping allows the organic components inside, the wood of a stretcher or the linen of a canvas, to moderate the humidity in the enclosed air space, as long as there are no extreme temperature variations in transit. Its method: condition the materials by storing hygroscopic ones such as cardboard in the painting's own environment for at least a day before wrapping; clear plastic sheet cut large enough to wrap completely around with about 8 cm of overlap at the back; rigid cardboard cut to the outside dimensions of the frame front, rigid enough not to sag and touch the painting; a second board on the back with folded overlapping edges, making a box.
On taping the glass, it gives both the practice and the evidence against it: tape the outside of non-laminated glass fully with low-tack tape so shards are held, and remove the tape slowly and soon after travel; but note that tests found damage to a painting was often similar whether the glass was taped or not. For glazed frames larger than a square metre it suggests replacing the glass with laminated glass to avoid damage from sharp pieces if it breaks.
Packing a small framed picture. A federal museum leaflet gives a step-by-step pack for framed objects no larger than 16 inches on any edge, with its exclusions stated first: use it for photographs, prints, watercolors and oil paintings in good condition with intact, uncracked glazing, and do not use it if the frame has loose areas, mold, surface damage, flaking surfaces, torn supports or buckling, if there is no glazing, or if the piece is a charcoal, pastel or soft pencil drawing, because those media are most vulnerable if not fixed. Its layers, in order: glassine or unbuffered tissue around the frame, not secured closed; urethane foam and corrugated board each cut half an inch larger than each side; folder-stock strips an inch and a half wide around the edges to stop the stack shifting; bubble wrap; then a box lined with two inches of foam on all four sides and the bottom.
And the thing that is not a procedure. A conservation institute's handling note says most damage to paintings and their frames happens during handling, and lists the causes: underestimating the weight of a framed painting; not seeking help, when most paintings require two handlers and a spotter; not using proper equipment and gloves; not planning a safe, uncluttered route; and not preparing a place to put the work down. Remove dangling jewellery and bags. Handle one at a time. Do not squeeze between furniture, because navigating sharp corners can easily pierce a canvas. For anything beyond a car boot, hire the people who do it; Plan Your House Move's comparison of moving service scopes covers finding them.
7. Recording, and what an insurer wants
Two records, with different jobs.
The condition record is what tells you whether something has changed. A conservation institute defines it for institutions: a written record detailing the condition of a painting and its frame based on close examination, which, used with photographs, clearly records physical condition at that time, and which, kept systematically, documents changes over time. It lists the changes it catches: natural ageing, accidental damage, vandalism, infestation, inappropriate display or storage, improper handling, inappropriate packaging for travel, and alteration from restoration treatment. And the occasions for making one: at acquisition, during storage, before display, periodically while on display, before and after travel, immediately after damage, before any treatment, and as part of a survey.
No source in this research writes a household version of that, at any scale smaller than an institution. So the condition sheet in Your pictures is our practice, built down from the institutional form to four things a household can actually sustain: a date, what you see on the front, what you see on the back, and a flag for anything that needs a conservator. Photographs do most of the work; the words are there so you can search them.
The inventory is what an insurer or an appraiser reads. A professional conservation body's guide on insurance names the contents: at least the creator's name, object title, date, physical description and an image, plus its location, condition and value. Two state insurance regulators give the household version: a complete list of your property will help you decide how much coverage you need and will make filing claims easier; record purchase date, value and serial number where possible; keep the list and receipts for major items in a fireproof safe or at another location; photograph or videotape each room, including closets, storage buildings and the garage. One regulator suggests updating the inventory at least three times a year or at the start of each season, and points to a regulators' association's free app.
Two words worth knowing before you call an insurer, from the professional body's guide. Scheduled coverage is based on agreed values for specific items listed on the policy; blanket coverage provides a total limit with a single article limit for each class, and collectors often choose a combination. For a blanket policy the guide says a current inventory list including values is crucial to the claims process, because the carrier will not have a list of the items covered and will rely on you to provide it. And the valuation distinction: fair market value is realized in the auction market, while retail replacement value, such as prices at retail galleries, is the type used for insurance policies, and replacement value can be as much as 100 percent above fair market value.
A state regulator adds one caution worth carrying: in insurance, "appraisal" also names a claim dispute process, where each side hires an appraiser and the two choose an umpire whose decision is binding. That is a different thing from an appraisal of an artwork, and the word means two things in one conversation.
Nothing in this manual values anything, and none of this is insurance advice. Your pictures holds no addresses and no account numbers precisely so it is safe to print and hand across a desk.
Go deeper 8. The paperwork worth keeping with a piece
Beyond the photograph and the row, four kinds of paper are worth keeping with a piece, and one state's law gives a good indication of what a seller should have given you in the first place.
New York's arts and cultural affairs law requires an art merchant selling prints and photographs for more than one hundred dollars each, exclusive of any frame, to furnish written descriptive information before the sale. What it must say is a useful checklist of what to keep: the artist's name; whether the artist signed the multiple, and if not, the source of the artist's name on it; the medium or process with relevant materials, and whether the purported artist was dead when the master was made; whether the image reproduces an image made in a different medium for another purpose; whether the piece is posthumous or made from a master that produced a prior edition; the year or approximate year of production; and, if it is offered as part of a limited edition, the number in the edition and whether and how each is numbered. That last statement is an express warranty that no additional numbered multiples of the same image exist beyond the edition size by more than twenty or twenty percent, whichever is greater, excluding trial proofs.
It is one state's law, cited here as a labelled example of the kind of paper worth having rather than as a rule anywhere else. Keep: the certificate or disclosure, the receipt, the framer's specification and dated order, and any conservation report. Scan them and keep the scans somewhere other than the house.
Appraisal, if you need one. Two bodies could be read in this research. An international society describes itself as a not-for-profit formed to advance education in personal property appraising and publishes a searchable directory; an American society describes itself as the oldest multi-discipline non-profit international organization of professional appraisers, with Personal Property as the discipline covering art, and its own find-an-appraiser directory. A third body could not be read: its site was behind a security challenge that neither a script nor a browser could clear during this research, so nothing about it is stated here. The professional conservation body's insurance guide says periodic appraisals by appraisers who follow the published practice standard are strongly recommended and may be required by some insurers above a value threshold.
Where to find a conservator. The professional conservation body maintains a find-a-conservator service, and both a federal agency and a museum conservator point households to it. Its own public guidance pages carry care guides for metal objects, photographs, textiles, glass and ceramics, and insurance; its paintings guide was listed as coming soon when this research was done, and works on paper appear only in an older series.
9. See it See it
The Okonkwos' first yearly check. A year after hanging, Nia spends twenty minutes on the wall of twelve. Known: the wall reads 450 lux at the brightest hour; the three irreplaceable prints were scanned and the originals are flat in a box; the twelve frames are 16 by 20 with acrylic glazing. Assumed: that nothing has changed, which is what she is testing. What she finds: two frames are no longer level, one D-ring screw has backed out a turn, and the acrylic on three of them has a haze of fine scratches from being wiped with a paper towel, which she now knows not to do. Nothing on the pieces themselves. She writes four rows in the findings sheet, tightens the screw, re-levels the two, and buys a microfiber cloth. Open: whether the scratches will bother her enough to replace the acrylic, which she leaves as a note for next year. Twenty minutes, four rows, and a record that will make next year's check mean something.
- Cleaning paintings: precautions, a conservation institute: the published list of what never to use, the reason, and the splash protocol.
- Emergency salvage of flood damaged family papers, the national archives: the framed-item rule, the drying method, and what not to freeze.
- Storage and display guidelines for paintings, the same institute: the figures for stacking framed work against a wall at home.
- Home insurance guide, a state insurance regulator: that home policies limit what they pay for art, what an endorsement is, and why an inventory matters, from a regulator rather than a seller.
10. Practice Practice
Minimum: one calendar date set and one piece recorded with a photograph. Time: about an hour once, then twenty minutes a year. Materials: a phone, a soft dry cloth, a microfiber cloth, and the care log.
- Put the date in your calendar now, as a yearly repeat. Add a link to the care log in the note. The check that is not scheduled does not happen.
- Walk the house once with the checklist and tick the ten lines. Write what you found, including nothing.
- Photograph each piece in place, front on. Keep the photographs with the picture file rather than loose in a camera roll.
- Fill in the rotation sheet for anything light sensitive. Give the measured level and the date to take it down (the rotation box).
- Export the picture file and put the copy somewhere else (Go deeper; optional). That is also the moment to check that the receipts and any certificates are scanned.
11. Your pictures Your pictures
12. Check your work Check your work
Criteria
- A recurring date exists in a calendar, not just an intention.
- Every piece has a photograph and a row, kept somewhere other than the house.
- Nothing has been cleaned except the outside of the glazing.
- Each light-sensitive piece has a rotation date and something to put up instead.
- Anything that needed a conservator went to one, and the record says when.
Worked example
Hal Brewer (fictional) finishes his year. The watercolor is on an interior wall at 90 lux, and the rotation box gives him a take-down date about eighteen months out at six hours a day, which he writes in the sheet with "the reprint goes up" beside it. His record holds the conservator's report, the framer's eight-line specification, a photograph of the front and one of the back before the reframe, and the receipt from the fair where his grandmother is thought to have bought it in 1961. He has not had it appraised and may not; he knows which body's directory he would use if he did, and he knows the difference between what an auction would realize and what it would cost to replace. Three pieces of paper and two photographs, scanned, kept at his daughter's house. That is a complete record for a household, and none of it required a valuation.
Common mistakes
- Spraying glass cleaner at a framed picture. Liquid runs behind the glazing. Dampen the cloth, away from the piece.
- Dusting the picture itself. The published prohibitions are about exactly this, and the reason is flakes you cannot see.
- Using a commercial picture restorer. A conservation institute says these are neither used nor recommended by professional paintings conservators.
- Leaning framed work in a stack indefinitely. A conservation institute says leaning is not a storage strategy, and gives figures for the temporary version.
- Keeping the only record in the browser. Browser storage is cleared, lost and not shared between devices. Export it.
- Treating a rotation date as a deadline from someone else. It is your plan, from published figures and your own reading.
What is still unresolved
- What any of it is worth, which an appraiser settles and this manual does not touch.
- Whether a specific blemish needs treatment, which a conservator settles.
- Exactly how long a sealed package holds humidity in a house, which nobody publishes for paper.
- How often a mat package should be replaced; one practitioner says matboard takes in pollution and should be changed periodically, and nobody gives a number of years.
