Cleaning sports cards
Dust can be removed. Creases cannot. And anything that counts as restoration makes a card unsellable at full value.
What is safe to do
Very little. A soft brush or a microfibre cloth can lift loose dust from the surface, and a dry, clean eraser can sometimes lift a pencil mark from a plain back — but both carry risk, and neither improves a grade.
The honest position is that cleaning rarely helps and often hurts. Anything that alters the surface can be detected, and a card that has been altered is graded as such.
- Loose dust: a soft brush, gently, from the centre outwards.
- Pencil marks on a plain back: a dry eraser, very lightly, at your own risk.
- Anything else: leave it alone.
- Never use water, solvents, polish or cleaning sprays.
What cannot be fixed
Creases, corner wear, edge chipping, foxing, print lines and surface scratches are all permanent. Some can be hidden by a skilled restorer, which is exactly why graders test for restoration — and why a restored card is worth less than an honest one with the same visible condition.
- Creases: permanent, and they cap the grade.
- Corner and edge wear: permanent.
- Foxing and staining: usually permanent.
- Trimming, recolouring, pressing: restoration, and it is detected.
Protect instead of cleaning
The only reliable way to improve a card's condition is to stop it getting worse: sleeve it, keep it dry, keep it out of light, and handle it by the edges. That is the whole method.
If a card has a problem you cannot fix, record it when you scan it. Then it is part of the card's record rather than a surprise for a buyer.

FAQ
Frequently asked questions
Can I clean my sports cards?
Only loose dust, with a soft brush, and it rarely changes a grade. Water, solvents, polish and cleaning sprays all risk altering the surface, and an altered card is graded as such and loses value.
Can creases be removed from a card?
No. Creases, corner wear, edge chipping and staining are permanent. Attempts to remove them count as restoration, which is detected by graders and makes the card worth less than an honest copy.
Why is a restored card worth less?
Because the alteration is a disclosure risk. Grading companies test for trimming, recolouring and pressing, and a card that fails is labelled as altered — which removes it from the market for collectors who want original cards.
How do I improve a card's condition?
You cannot, beyond preventing further damage: sleeve it, keep it in a cool, dry room away from light, and handle it by the edges. Record any existing flaws when you scan the card, so a buyer knows what to expect.
