Hello, I am new to this gaming community. I just started collecting old Nintendo NES games and got my old console a brand new 72 pin installed. Now I have started cleaning my NES games. I have used polishing paste and finished them off with little bit of alcohol. I know cleaning by hand is time consuming and probably the safest way to clean them. So I have tried another method of cleaning them. I have tried buffing them with dremel in low rpm setting. It appear to be effective and of course, the quickest way to clean game chip. But the question is, does using dremel affect the quality of game play? Is this method a wise idea? I am curious what is your cleaning method, especially quickest way to do it? I have ton of games to clean and cleaning them by hand isn't gonna be fun.
