I'm trying to get my system as clean as possible. I have scrubbed the case to remove all dirt and gave it a coat of, no not Armor All, I used Formula 2001. but I would like to get the contacts as clean as possible too. so, if you can help me in any way I would really appreciate it. thank you.

I use a stainless steel ruler (1/16" thick) with 600 grit sanpaper wrapped around the end and slide it into the load slot a few times and blow it out with compressed air and you are good to go.
