Does that need to be disclosed at risk of committing a criminal act?

The natural state of the Topps cards I collected in the 1960s came in wax packs. Sometimes the gum was lightly stuck to a card, and I altered that original, from-the-factory natural state by separating the gum from the card.
Often, powdered sugar residue might be in a card, and I'd wipe it off. If there was wax residue on a card back it left a stain and there wasn't much I could do, but if it was on the glossy side, I removed wax by rubbing it with a cloth.

It's a slippery slope, which is why I say the word "cleaning" is much too ambiguous.

Clearly your examples are not cleaning and clearly I was writing to Snowman about his type of cleaning that he has detailed repeatedly. Assuming he is being truthful about what he really does to clean cards, he has clearly defined what cleaning is to him.
