How to Clean Trading Cards Safely: Fingerprints, Dust, Haze and Residue

Most cards that need a clean just have fingerprints or dust on them. Chrome cards like Panini Prizm and Topps Chrome are the worst for it, because one touch on the front leaves a print you can see straight away. Nearly all of it comes off with a clean, dry microfibre cloth and a light touch. Plenty of the cleaning advice online goes well past that, and some of it can damage a card or get it marked as altered by a grader.

Below is what's safe, what isn't, and how to clean each type of card. The rule we go by: start dry, go gently, and stop if it isn't working.

Cleaning vs altering: where the line is

Cleaning removes something sitting on top of the card, like a fingerprint, dust or a smudge, and leaves the card itself exactly as it was made. Altering changes the card. On MVCollect, cleaning is fine and altering isn't. Raw cards that have been altered can't be listed here, even with it disclosed. Altering includes:

• Pressing: flattening creases, dents, bends or wrinkles, with or without heat and moisture.
• Recolouring and touch-ups: ink or marker on worn edges and corners, or colouring in print flaws.
• Trimming: cutting an edge or corner to make it look sharper.
• Re-glossing or coating: adding wax, polish, gloss or any coating to make the surface shine.
• Filling: filling dents, chips or missing paper.

See how to spot restored cards for how each of these shows up.

How graders see cleaning

Graders haven't set out every detail, so this is what they've said publicly:

• A dry wipe is widely accepted. Collector guides, grading-prep sites and card shops all agree that gently wiping a fingerprint or dust off with a dry microfibre cloth is normal care. PSA's president Ryan Hoge has said PSA graders already sometimes wipe fingerprints and smudges themselves, and in 2025 PSA surveyed customers about a possible cleaning service that would mainly involve wiping off fingerprints, smudges and dirt (Sports Illustrated, October 2026). We haven't seen that service launch.
• Products on the surface are a real risk at PSA. PSA's grading standards treat a card as altered when a foreign substance, such as a cleaning spray or wax, is applied to its surface, and also when a solution has been used to remove wax, gum, candy or tobacco stains. Hoge said in 2024 that PSA doesn't approve of any chemicals or foreign substances being added to a card, and that if PSA detects it, it will consider the card altered (Cardlines, 2024).
• An altered card loses its number grade. PSA and Beckett both give cards they find altered an "Authentic" or "Altered" result instead of a number, which is usually worth far less than even a low grade.
• Collectors still disagree about everything in between. Specialist card-cleaning businesses say their products are made for cards and don't alter them, and some cards cleaned that way have since been graded with no altered note. Other collectors and grading-prep guides say no liquid of any kind should touch a card. Graders' detection methods aren't public, and the rules could change.

Our advice: stick to a dry cloth, a soft brush and a puff of air. Anything wet, or any cleaning product, is a risk, especially on a card headed to PSA. If you sell a card on MV that's been cleaned with anything more than a dry cloth, mention it in the description. Buyers like knowing.

The tools you need (and what each is for)

Looking after the cloth: a dirty cloth just moves grit around and can scratch. Keep it in a zip-lock bag between uses, shake it out before each card, and wash it often in warm water with a little plain detergent. Skip fabric softener: it coats the fibres, leaves residue and makes the cloth less effective. Air-dry it, and replace it once it stops feeling soft.

What never to use, and why

• Paper towels, tissues, napkins and toilet paper. They're made of wood fibre, which is rougher than it feels. It can leave fine scratches on chrome and holo, and it sheds lint.
• Your t-shirt or jumper. Clothing holds grit and dust, and the threads are coarser than microfibre.
• Household sprays and wipes (glass cleaner, multipurpose sprays, baby wipes, screen wipes). They leave residue, can soak into card stock, and are exactly the kind of foreign substance graders treat as alteration.
• Alcohol, acetone and nail polish remover. They can dull or strip gloss, lift ink and damage foil. They also count as a foreign substance to PSA.
• Water, and breathing on the card. Card stock is paper. Moisture can make it ripple, curl or warp, and your breath adds moisture and saliva.
• Erasers. An eraser works by rubbing away a thin layer of surface. On a card that means gloss, ink or paper. Collector and grading-prep guides list erasing among the things that can get a card marked altered. (An eraser is fine on a slab's plastic case, just never on the card itself.)
• Anything abrasive: scourers, the rough side of a sponge, polishing compound, toothpaste, magic erasers (melamine sponges, which work like very fine sandpaper).
• Polish, wax or "shine" products. These are re-glossing, which is altering, not cleaning.
• Canned compressed air. If the can tilts it can spray freezing liquid propellant onto the card. A rubber bulb blower does the same job safely.
• Fingernails, blades or tweezers to pick at specks. One slip and you've made a dent or scratch that's there forever.

Step by step, gentlest first

Do these in order and stop as soon as the card is clean. Most cards never get past step 3.

1. Look first. Wash and dry your hands, then hold the card by its edges and tilt it under one light. Work out what you're actually looking at: a fingerprint or dust (on the surface, can be cleaned), or a scratch, print line, dent or stain (part of the card, can't be cleaned).
2. Air. Lay the card flat on your soft surface and give it a few puffs with the bulb blower. This removes loose dust and grit, which matters because wiping over grit is how scratches happen.
3. Brush. If specks remain, sweep them off with the soft brush, lightly, in one direction, off the edge of the card.
4. Dry microfibre wipe. Fold the cloth so you're using a clean section. Hold the card steady by the edges, or flat on the soft surface, and wipe gently in straight strokes in one direction, from the centre out to the edge. Use only enough pressure to move the cloth. Turn to a clean part of the cloth often. Don't scrub back and forth, and don't rub in small hard circles.
5. Check again under the light. If the mark is gone, you're done. If it's still there after a few gentle passes, stop. Pushing harder won't help a dry wipe, and it can mark the surface.
6. Anything past this is up to you, and it's a risk. Some collectors use a barely damp cloth or a card-specific cleaning product for stubborn marks. Graders can treat that as a foreign substance, so we don't recommend it for any card you plan to grade at PSA. If you do go further, test on a low-value card first, put any product on the cloth and never on the card, use the smallest amount possible, and disclose it when you sell.

Card type by card type

Chrome, Prizm, Optic, Select and refractors

These have a shiny, smooth face that shows every fingerprint, but it's also the easiest surface to clean. A dry microfibre wipe usually takes prints straight off. Watch out for two things: the backs are often normal card stock that's less forgiving than the front, and refractor and Prizm parallels can have fine factory scratches and "roller lines" that look like haze but are part of the card. If a gentle wipe doesn't shift it, it's most likely part of the card.

Standard paper stock

Most base cards and older footy cards are matt or lightly coated paper, and paper soaks up skin oil. A fresh fingerprint can sometimes be lifted with a very light dry wipe. An old one has often soaked in and won't come out. Air and a soft brush are the safest choices here, and be extra gentle with the cloth, because rubbing can scuff or polish a matt surface.

Foil, holo and Pokémon cards

Holo and foil layers scratch more easily than they look, and scratches on holos show up badly under light and in grading. Use air first, then the lightest single wipes with a clean cloth and almost no pressure. Never rub the holo hard. Leave alone anything that's part of the print, like small ink dots, print lines or specks under the surface; trying to scrub them out only damages the card. The same goes for One Piece, Magic, Yu-Gi-Oh! and other TCG holos and foils.

Textured cards

Some modern Pokémon and TCG special art cards have an etched or textured surface. Brush with the texture rather than wiping across it, because cloth fibres can catch in the grooves.

Vintage cards

Old cardboard is fragile, absorbent and often already worn. Stick to air and a very soft brush, and only wipe if the surface is coated and the mark is clearly sitting on top. Don't try to remove wax, gum, tobacco or other old stains: PSA's standards specifically count using a solution to remove those as alteration, and on old paper the stain is usually soaked in anyway. Most vintage collectors would rather have an untouched card with a stain than one that's obviously been worked on.

Autographed cards

Never touch the signature. Don't wipe over it, brush across it or put anything on it. Marker ink can smear, lift or fade, and a damaged or retraced signature can wreck the value. Clean only the parts of the card well away from the autograph, or just use air. On sticker autos, avoid the sticker's edges too, because they can lift. For signed memorabilia, see how authentication works.

Patch and relic cards

Don't press on the window or the swatch: the window frame can crack and the material can pull. Blow dust out of the window with the bulb blower rather than brushing it. Never pick at loose threads or try to clean the fabric itself, and never try to reseat or re-stick a patch. That's altering. Wipe only the flat card surfaces around the window.

Numbered cards

Serial numbers are often stamped in foil, which can rub off with too much friction. Wipe around the number, or over it with no pressure at all.

Fixing specific problems

Fingerprints

Dry microfibre, straight strokes, light pressure, clean section of cloth. On chrome this nearly always works. On paper stock, fresh prints often come off and old ones often don't.

Dust and specks

Air first, brush second, cloth last. Dust in a photo or under a sleeve usually looks worse than it is.

Haze or a cloudy film

Work out where it is. Take the card out of its sleeve or holder and check whether the haze is on the holder. Often it is. On the card, a light film from handling may come off with a dry wipe. A greasy or cloudy film from old soft PVC sleeves or pages can be very hard to remove, and haze that's in the print or coating at the factory can't be removed at all. If a few gentle dry passes don't shift it, leave it and show it in your photos.

Price stickers and tape on the card

Pulling a sticker or tape off a card can tear or lift the paper surface, and using solvents to dissolve adhesive puts a foreign substance on the card. For a valuable card, the safest choice is usually to leave it, describe it honestly and let the buyer decide, or get advice from an experienced dealer first. If you decide to remove one, test on a cheap card first, peel slowly at a low angle, and stop if any paper starts lifting. Gentle warmth from a hair dryer on low, held well back, is a common household way to soften adhesive, but heat can also curl a card, so use it sparingly and never on chrome or foil.

Sticky residue on sleeves, toploaders and slabs

If the gunk is on the holder rather than the card, the easy fix for a sleeve or toploader is to replace it. They cost cents. For slabs, see the tape gunk section of how to photograph cards to sell: an eraser or rolling it off with your thumb usually works. Always take the card out before cleaning a sleeve or toploader.

Toploader scuffs and scratches

Marks that look like scratches on a top-loaded card are often on the toploader. Take the card out and look again. If the toploader is scuffed, bin it and use a new one. If the scratch is on the card, it can't be cleaned off. Polishing a scratch out is altering, and PSA's altered-card rules are widely reported to include scratch removal and added gloss.

What cleaning can't fix

Cleaning only removes what's sitting on top. These are part of the card, so show them clearly in your photos instead:

• Scratches and scuffs in the surface
• Creases, dents, bends, wrinkles and warping
• Edge and corner whitening, chipping and soft corners
• Factory print lines, roller marks, ink dots and off-centring
• Stains soaked into the card, water damage and fading
• Old fingerprints that have soaked into paper stock

"Fixing" any of these is altering, and a raw card that's been altered can't be listed on MV.

Before sending cards for grading

• Clean each card right before you sleeve it, not days earlier, so it doesn't pick up new dust or prints.
• Dry methods only for anything going to PSA. Don't risk a number grade for the sake of a smudge a grader may wipe anyway.
• Use a fresh, clean penny sleeve and a clean semi-rigid holder (the kind graders ask for), and handle cards only by the edges.
• Check each grader's current submission rules before you send. See getting cards graded from Australia for the options.

Before photographing a card for a listing

• Phone cameras pick up every speck. Blow off dust, give the card a gentle dry wipe, and clean the sleeve, toploader or slab too.
• Take your photos straight after cleaning, under the same light you used to check it.
• Don't clean a card to hide a flaw. Show scratches, dents and whitening clearly so the buyer knows what they're getting.
• If you've cleaned it with anything more than a dry cloth, say so in the description.
• For lighting and angles, see how to photograph cards and slabs to sell. For slabs, it's also worth reading how to check a graded slab is genuine, since buyers will be checking yours.

Handling and storage, so you don't have to clean

• Handle by the edges with clean, dry hands. Never touch the face of a chrome or holo card.
• Sleeve cards straight out of the pack if they're worth keeping, especially chrome and holos.
• Use PVC-free sleeves, pages and toploaders. Polypropylene and polyethylene are the materials collectors trust. Old soft PVC pages are well known among collectors for leaving a greasy, cloudy film on cards over time. If a product doesn't say what plastic it is, be wary.
• Use the right toploader size. Thick patch and relic cards need thicker toploaders (55pt, 75pt, 100pt and up). Forcing a card into a tight one scuffs and bends it.
• Keep cards cool, dry and steady. The Library of Congress recommends a cool, stable, fairly dry spot (around 35% relative humidity) for paper items, away from attics and basements. Here, that means not in the garage, the shed or a hot car. In humid places, like much of Queensland and the Top End, many collectors keep silica gel packs in their storage boxes and check them regularly.
• Keep them out of the light. Sunlight and fluorescent light fade cards and, especially, autographs over time, even behind UV-protective cases.
• Avoid rubber bands, paper clips and screw-down holders done up too tight. All of them can dent or bend cards.

Common mistakes that damage cards

• Wiping before blowing the dust off, which drags grit across the surface.
• Pressing harder when a mark won't move. If it doesn't come off gently, it probably won't come off at all.
• Using a dirty, old or fluffy cloth, or one washed with fabric softener.
• Grabbing whatever's nearby: a shirt, a tissue, a paper towel.
• Spraying anything onto the card, or breathing on it to fog it up.
• Rubbing over a signature, a sticker auto or a foil serial number.
• Trying to "fix" a scratch, crease or stain, which turns a flaw into an alteration.
• Cleaning a holo or chrome card on a bare table, where it can pick up a scratch from the surface underneath.

Quick checklist

1. Clean, dry hands (or nitrile gloves). Soft, clean surface.
2. Look under one light: is it on the card, or part of it?
3. Air blower first.
4. Soft brush for anything left.
5. Clean, dry microfibre: light, straight strokes, one direction.
6. Check again. Still there? Stop.
7. Never touch signatures, patches or foil numbers.
8. No liquids, sprays, alcohol, erasers or polish on the card.
9. Sleeve it straight away in a clean, PVC-free sleeve.
10. Selling? Disclose anything beyond a dry cloth, and show every flaw.
