Cleaning for Grading

Cleaning for grading involves the safe removal of surface contaminants from trading cards before professional submission. When done correctly, cleaning can improve presentation and potentially increase grades. When done incorrectly, it can damage cards, result in altered status, or cause outright rejection by grading companies.
