Followup to the rusty NES board, giving the shell a good clean. My process is to soak the shell in hot, soapy water for a while, then clean it using different brushes and cloths. This one has enough damage and stains in the plastic that I’ll probably need to paint it to make it respectable again.
I like to avoid using a magic eraser since that is basically taking a fine sandpaper to the shell.
Thanks for warning folks off aggressive use of magic erasers. There are many NES shells that are mirror finished now because magic erasers wore off the texture of the molding die.
