Best is a pink eraser or white art eraser. After that I use Deoxit D5 with a qtip before I play it to clean both the system and cart at the same time by inserting the cart 5 times before powering it on.
I have no idea what the hell rubbing alcohol is supposed to achieve, you need to remove the oxide not sterilise it. Personally I use brasso polishing wool, followed by PCB cleaner on a paper towel, works a treat.
