I agree with your fix. It makes it much more true.

I use rubbing alcohol and a qtip, if that doesn't work i open it up and use an eraser, then wipe it down with windex.

I've used 2000 grit and 800 grit. 2000grit works great because you don't want to remove a lot of surface material, but it's hard to fun at the local store. It does polishes up the contacts real nice though
