Just happened? Do this first
- Pick up spills and excess epoxy with paper towels before it cures.
- On skin, use a waterless skin cleanser on the resin, then wash the hardener off with soap and warm water. Never use solvents.
- If epoxy gets on your clothes, change them right away.
Epoxy on paper leaves you with fewer options than most stains, because paper can't take water or solvents and the hardening is a chemical reaction that home methods won't undo. Your first call is whether the item is worth treating at all, since a valuable sheet or photo may deserve a professional's hands. Anything you attempt at home should stay dry and gentle.
Keep the work dry and test a hidden edge first, since paper reacts to almost anything wet. Photographs and negatives need a lighter touch than brittle paper or flaking ink. Treat dried epoxy on paper like easing a picture hook off plaster: slow, dry and with as little force as possible.

7 steps
Step by step
Step 1 of 7
Decide whether to treat it
Ask first whether the piece is worth treating at all. If it is valuable, has progressing damage or is handled often, a paper conservator is the better choice than any home method.
Step 2 of 7
Dry wet paper before anything else
If the paper is wet, spread it out to air dry right away, somewhere cool and relatively dry and away from radiators and vents. If it can't be air dried within two days, freeze it instead.
Careful. Never freeze old photographs or negatives.
Step 3 of 7
Handle it with clean hands
Wash your hands and dry them before you touch the item. Hold photographs by the edges or wear clean nitrile gloves, and keep your fingers off the image. If epoxy or wet foam reaches your eyes, flush them with water for 15 minutes and seek medical attention if discomfort persists.
Step 4 of 7
Blow dust off photographs
If the item is a photograph, remove only loose dust with an air-bulb blower. Paper doesn't need this step, so skip it there.
Careful. Don't use canned air on photographs.
Step 5 of 7
Test a hidden spot first
Before you brush or erase anything, test a small, unobtrusive spot. Watch closely for smearing or lifting of ink or graphite, and stop if you see either.
Step 6 of 7
Brush away loose debris
Brush loose debris off with a clean, soft natural-bristle brush. Work from the inside of the sheet toward the edges so the debris moves off the paper rather than across it.
Step 7 of 7
Rub with vinyl eraser crumbs
Grate a non-colored vinyl eraser into crumbs, then rub the crumbs over the spot in short, random strokes. Once the loose grime is gone, stop, because surface cleaning won't go further.
Tip. Check the sheet under good light after each pass so you don't overdo it.
Careful. Don't use a block, putty, electric or commercial abrasive eraser.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
You're on track when the loose dust and debris lift with no smearing or lifting of ink or graphite. If the mark stays after the eraser crumbs, stop: surface cleaning will not remove heavy soiling or staining that has become embedded, such as tide lines, mold stains or mat burn.
What changes for yours
Adjust for your paper, books & photos
Photographs and negatives
For photographs, the only step is the air-bulb blower on loose dust, and the brush and eraser stay off the image. Hold each print by its edges, and keep your fingers off negatives too.
Dampening a photograph to lift a mark is never a home method here, because photographs can't take water. If the mark is still there after the blower, a photograph conservator is the right person to ask.
Brittle paper and flaking ink
Brittle paper, flaking ink and hand-colored items should not be surface-cleaned at all. Skip the brush and eraser steps for them, and handle the sheet as little as possible.
A paper conservator is the safer call, since a wrong move can lift the ink or color you want to keep. Keep the item in a cool, relatively dry place while you wait.
Pencil, pastel and charcoal
Loose pastel, pencil and charcoal fall on the do-not-surface-clean list, so the brush and eraser steps don't apply. Store the drawing flat in a cool, relatively dry place while you decide what to do.
If the drawing matters to you, the decision in the first step counts most. A conservator can tell you whether anything safe is possible.
Books and bound pages
Pages still bound into a book are a different job from loose sheets, and the crumb method is not for them. Keep bound pages closed where you can, and check with a conservator before touching anything in the binding.
Once a sheet is out of the book, treat it like any other sheet and start with the first step. If the stain is still there after that, a conservator is the next call.
Old, dried or set-in stains
Old spills that have cured are the hardest case. Everything in this group is far easier to remove before it cures, so the steps above are for fresh or loose material.
Stains that have dried into the paper, such as tide lines, mold stains or mat burn, count as embedded. Home surface cleaning does not remove them, so rubbing harder only risks more damage. Tape residue, insect excretions and rust deposits need a conservator too.
If the mark is still there after the steps above, accept that it may stay. For items of collector's value, the better choice is to leave them as they are and improve storage. For mold stains only, keep humidity between 40-65% so the mold does not regrow.
Vinegar, baking soda, peroxide and more
Do home remedies work on epoxy on paper, books & photos?
Most household remedies are liquids, and paper can't take water or solvents. Avoid nearly all of them. Salt is only a Skip because it doesn't apply to this stain.

What makes it worse
Mistakes to avoid
Don't wet the paper to clean it
Paper can't take water, hot water, soaking or solvents, so a damp cloth can do more harm than the stain. Soaking stuck-together wet prints in cold water could cause irreversible damage, so don't try to pull them apart that way.
Don't put tape or glue on photographs
Self-stick tape can be extremely difficult to remove, even when it is marketed as 'archival'. Keep tape, sticky notes, glue and 'magnetic' self-adhesive album pages away from photographs too.
Don't use eraser crumbs in books
Eraser granules get trapped in the gutter of a book and are hard to get out again. The crumb method is for loose sheets only, so keep it away from anything bound.
Don't try to remove active mold
Brushing or rubbing active mold may only spread or smear it. If you see active mold, leave it alone and bring the item to a conservator.
When to call a professional
Consult a paper conservator, or a photograph conservator for photos, when the item is valuable, has progressing damage, is handled often, or shows embedded stains, tape residue, insect or rust deposits. If you're unsure, that's reason enough to ask. Items of high monetary, historic or sentimental value should be treated only in consultation with a conservator.
Questions
How do I remove picture hooks without damaging plaster?
Plaster is a wall surface, and the paper methods here can't be used on it. The Walls stain guide is the right place to start.
Can I use water on epoxy on paper?
No. Paper can't take water, hot water or soaking, so keep the sheet dry and work with the brush and vinyl eraser crumbs.
Can I use vinegar or rubbing alcohol on paper?
No. Vinegar is water-based and rubbing alcohol is a solvent, and paper can take neither. Stick to the dry steps above.
Should I freeze wet paper?
Only as a fallback. Spread wet paper out to air dry right away, and freeze it only if it can't be air dried within two days.
Can I use an eraser on epoxy on paper?
Yes, but only a grated, non-colored vinyl eraser, rubbed as crumbs in short, random strokes. Test a hidden spot first, and stop if ink or graphite smears or lifts.
When should I call a paper conservator?
Call one when the item is valuable, has progressing damage, is handled often, or has embedded stains, tape residue, insect or rust deposits. If you're unsure about the item, ask before you try anything.
Will surface cleaning remove embedded stains?
No. Home surface cleaning won't remove embedded staining such as tide lines, mold stains or mat burn. For a valuable item, ask a conservator rather than rubbing harder.
