Went to play some Tri-Zone a bit ago and it didn't work. Doh! Never took the batteries out.... not a lot of damage so I'm going to give this method a go at it. Looks like it will work great.
Everyone mentions a brass brush..... anyone tried the brass brush wheels that you can get for a dremel tool?
Seem's like a no brainer there, but maybe there could be some issues if you have the dremel on too high of a speed. Might be quicker over all though if you get the speed/pressure right. Going to give it a go sometime soon and see what happens.
I already use these guys for cleaning up connector pins and chip legs.
Especially on the large EM plug connectors. You can get in between the pins with ease and shine them up real good for a like new connection. No more flickering lights!
