Should you clean or restore a card before grading?

It's one of the most common questions we get: will cleaning or restoring my card actually help its grade? The honest answer is sometimes, and knowing the difference matters, because grading is expensive.

What grading rewards

PSA, BGS, CGC and SGC assess four things: centering, corners, edges and surface. Two of those (surface and, indirectly, edges) can be improved by careful, non-destructive cleaning:

• Surface dirt, grime and fingerprints make a card scan worse than it is.
• Sticky residue and light debris can hide the true surface.
• A warped card presents poorly and can be marked down.

Removing dirt or flattening a warp doesn't change the card, it reveals the card that's already there. That's conservation, and it can genuinely help.

What it won't fix

Restoration is not magic. It cannot:

• Rebuild torn or missing pieces
• Erase deep creases through the card's layers
• Recolour faded or scratched print
• Guarantee any specific grade

If a card's problems are structural, cleaning won't move the needle, and we'll tell you that before you spend a cent.

The honest line

There's an important distinction between conservation (cleaning, flattening) and alteration (adding material, recolouring, trimming). Grading companies detect and penalise alteration, and some will refuse the card entirely. We only do conservation-grade work, and we're transparent about it, because your card's long-term value depends on it.

So, should you?

A good rule of thumb:

• Dirty, sticky, warped or grimy? Cleaning and flattening will likely help, worth doing before you grade.
• Torn, creased, water-damaged or trimmed? No amount of restoration changes the grade. Grade it as-is or keep it raw.
