Hi everyone. I purchased a Sears Video Arcade II a while back and opened it up to find a lot of rust on the RF shield and the areas where it touches the motherboard. I ended up soaking the RF shield in vinegar and painting it to try and give it some life back, at least until I can find a replacement. It was pretty bad and there was no way it would keep the factory shine after removing the rust in any way. I've been cleaning up the areas on the motherboard that I mentioned with 91% alcohol and switching between using a toothbrush, a Q-tip, and those blue shop paper towels soaked in the alcohol, but there is some rust that is being stubborn to come off. I wanted to get some advice on how to get the remainder of the rust off, or if you all think it won't be possible. I've included some pics to show what I'm dealing with. Thank you in advance for all your help and input.
