Short answer
Do as little as possible. Blow off loose dust, leave anything that doesn't come off easily, and let the grader see the card as it is. A fingerprint is a minor surface issue. A scratch from scrubbing, a dull patch from a cleaning spray, or a "cleaned" verdict from the grader is a much bigger one. TAG even lists fingerprint removal and dust removal as part of its own card care step, so for TAG submissions there is little reason to touch the surface at all.
What you can safely remove
| Problem | Safe to address? | How |
|---|---|---|
| Loose dust or lint | Yes | Hand air blower, a few short puffs |
| Light fingerprint on a glossy or holo front | Sometimes | One light pass with a clean, dry microfiber, no pressure. Stop if it smears |
| Grit stuck in the sleeve | Yes | Replace the sleeve, not the card |
| Stains (food, wax, gum, tobacco) | No | Leave it. Removing it is what PSA calls Evidence of Cleaning |
| Yellowed or dirty white borders | No | Leave it. Whitening borders is listed by PSA as cleaning |
| Pencil, pen or ink marks | No | Leave it. PSA uses the MK qualifier for marks, and erasing can make it worse |
| Bends, dents and creases | No | Leave it. CGC lists pressing as an alteration |
The pattern is simple. If it sits on top of the card and moves with air or a feather-light touch, you can deal with it. If it is in the card, on the card stock or needs a product to remove, leave it alone.
Tools: microfiber, air blower, soft brush and gloves
- Hand air blower. The rubber bulb kind sold for camera lenses. It moves dust without touching the card and without any propellant.
- Microfiber cloth. New or freshly washed with no fabric softener, kept in a bag so it stays clean. A dirty cloth just drags grit across the surface.
- Soft brush (optional). A clean, soft lens brush for dust on the edges. Never on a holo surface with pressure.
- Clean hands or powder-free nitrile gloves. Wash and dry your hands first. Gloves keep new prints off the card.
- A clean, soft work surface. A clean playmat or a microfiber cloth laid flat. A bare desk can scratch the back as you move the card.
- Fresh penny sleeves and semi-rigid holders ready to go, so the card goes straight back into protection.
Skip canned compressed air. Tilted or shaken cans can spit cold liquid propellant, which is exactly what you don't want on a card surface.
Step-by-step method
- Photograph the card firstTake a straight-on photo of the front and back, plus one at an angle under a single light so scratches and prints show up. This is your before record.
- Wash your hands or put on glovesDry hands completely. Lotion or moisture leaves new marks.
- Take the card out of its sleeve carefullyWork over your soft surface. Hold it by the edges, never by pressing the face.
- Blow off loose dustHold the card at an angle and give the front and back a few short puffs from the hand blower. For most cards, you stop here.
- Check under the lightTilt the card. If a fingerprint is still clearly visible on a glossy front, decide whether it is worth touching. If you're unsure, leave it.
- If needed, one light microfiber passLay the card flat on the soft surface, support it with a finger on the edge, and draw a clean section of the dry cloth across once in a single direction with almost no pressure. Do not rub in circles and do not repeat over and over. If the print smears or doesn't lift, stop.
- Sleeve it right awayPut the card in a fresh penny sleeve, then a semi-rigid holder for submission.
- Photograph it againTake the same angled photo and compare. If anything looks duller or scuffed, you have learned something before the grader did.
What never to do: liquids, erasers and pressing
- No liquids of any kind. Water, alcohol, glass cleaner, lens spray and baby wipes all count. PSA's definition of Evidence of Cleaning includes using "a solution" to remove stains and applying any foreign substance to the surface, such as cleaning spray or wax.
- No erasers. CGC lists power erasing as an alteration. Rubbing an eraser on a card can also lift ink and gloss.
- No whitener on borders. PSA names whitener on borders as cleaning.
- No pressing or flattening. CGC lists pressing among the alterations that keep a card out of a numeric grade.
- No shirts, paper towels or tissues. They are rougher than they look and can leave fine scratches on holo and glossy surfaces.
- No hard scrubbing, even with microfiber. Pressure turns a fingerprint into a surface scratch.
- No trimming. Not even a stray fiber on an edge. Trimming is the first no-grade reason on PSA's list.
Holo and vintage cards
Holo, reverse holo and full art cards show every flaw under light, including the fine scratches that come from wiping. Treat them as blower-only unless a print is obvious. Textured full arts have raised patterns that trap fibers if you wipe them, so air is the safer tool there too.
Vintage cards (WOTC era Pokémon, older sports cards) have softer, more absorbent stock and often have age toning, wax or gum residue. All of those are part of the card now. Removing wax or gum stains is specifically on PSA's Evidence of Cleaning list, and cards that were cleaned can come back without a number. On vintage, the safe move is dust only.
What graders treat as alteration
Here is what the major graders say, in their own terms, as of October 18, 2026.
- PSA. Its grading standards say PSA will not grade cards that show evidence of trimming, re-coloring, restoration or other tampering. Its no-grade list includes N7 Evidence of Cleaning, defined as using whitener on borders, using a solution to remove wax, candy, gum or tobacco stains, or applying any foreign substance like cleaning spray or wax to the surface. The grading fee is still charged. At the grader's discretion, and only if you listed "AA" as your minimum grade, such a card can be slabbed as "Authentic Altered."
- CGC. Its Cards We Grade page says a card found to be altered in any form, or cleaned or restored, will not receive a numeric grade and will not be encapsulated in a CGC holder. It lists trimming, restoration, power erasing, chemical cleaning, pressing and stain removal as evidence of alteration, and charges the grading fee for cards returned that way.
- TAG. Its service pages list fingerprint removal and deionization (dust removal) under card care. That is a reason to leave light prints for TAG to handle rather than try yourself.
We did not find a published cleaning policy on Beckett's or SGC's pages that we could load today, so check with them directly before submitting. In practice, assume every grader treats anything beyond dust and light print removal as a risk.
An altered card is worth less than the same card with its original flaws. A 7 with a fingerprint is still a 7. A cleaned card that comes back "Authentic Altered," or without a grade at all, has lost most of its graded value and you still paid the fee.
Check the surface before and after with photos
Your before and after photos are the only way to know whether cleaning helped. Use the same light and the same angle. A single desk lamp at about 45 degrees shows prints and scratches better than overhead light. Zoom in on the holo area and the corners. If the after photo shows new hairlines or a dull patch, stop cleaning other cards the same way.
The same photos are useful for pre-grading. Check the card against the card grading criteria graders use, then run the front and back through Binder AI, which returns a grade estimate on the PSA, BGS or TAG scale with a surface subgrade and written condition notes. It is an estimate, not an official grade, but it can flag surface issues you would otherwise only notice under a grader's lamp. Our pre-grading guide walks through the full routine, and once the card is clean and checked, how to store cards before grading covers sleeves, holders and packing.
