Started to used a rubber/eraser along with WD40 now.The contacts look pretty bad ass now.
I have one game that was pretty fucked up. TMNT IV. The front of the cart itself was in pretty good condition, the back could do with replacing, but that's another topic. The thing I wanted to talk about was the contacts. I bought this game on ebay, and it looked in pretty good shape, so for £20, I though I'd give it ago. Got it in the post and was a little let down with the back of the cart. I opened it up to give it a clean, lo and behold, there was something on the contacts that looked like rust... I gave it a clean with WD40 and removed a lot of dirt and grime, but it was still a bit rough in area's. I was getting nothing else off with each new que tip being clean. It bugged me but I let it go as it was working.
After a few months of game playing, I decided it was time to clean my games up again, and since I had just bought a tri wing screw driver, I can now give my GBA games a good and proper clean, so I had another good reason to give everything a good clean. I got to TMNT IV, opened it up, bar the dirt I couldn't get up, the contacts were still gleaming, but seeing the dirt, it annoyed me. I tried using an eraser in combination with WD40. I shifted some of the dirt, but not all of it, so I decided to use some Brasso after reading Wiggys comment... Fuck tons of dirt came off the game, I went through 4-5 que tips easy, but the contacts started to go from a bronze color to a silvery color with a yellow/bronze hue... I shit a brick, cleaned the brasso off, gave it a coat of WD40, put the board back into the cart and put it back in its UGC... I haven't tried to play it yet...
