[quote name='DuelLadyS']For cleaning most systems, I have good luck wrapping a disposable CD cloth around some sort of card (I use an old gift card), taping it into place, and applying a bit of diluted alchohol. Just pull it in and out like a cart, making sure to get both sides.
I dunno an easy way to do the front-loading Nintendo, since I got lucky and found a Nintendo brand cleaner at a flea market that was never used.[/QUOTE]
That's a great idea. I've used cardboard soaked in rubbing alcohol before, but I think this would be a much better setup.
And as for the NES, they are pretty easy to take apart. (No special tools needed.)
