Hi folks.

Wondering if anyone here knows a good way to clean and restore
life to the rotary cam finger switches like are used in Tek SC502,
SG503 etc.

I don't have any of the blue and the red CAIG fluid anymore but
to anyone here who ever used it what do you think of the stuff??
I had two little bottles with a built it applicator brush and I
thought the stuff worked great!

My SG503 went bonkers and I used spray isopropyl alcohol and then
a small shot of WD-40 on the contacts. Seems o.k. now.
