I noticed that Walmart sells a aerosol can of what is called "Contact Cleaner". (For electrical switches and stuff like that). I have never used it.
In the old days I used Radio Shack's contact cleaner. These days I use Deoxit, and I think Deoxit is a great product. But Deoxit is quite expensive, and has to be mail ordered. For expensive electronics, potentiometers, and similar, I'll use Deoxit, but for common slide switches, push on connectors, and other non-critical items, I'd like something cheaper to use, and easier to buy.
I have to wait till I get ot Walmart again, but if I recall, I think the brand is GC Electronics, and it sells for about $5 to $6 a can. It's sold in the automotive department (along with other chemicals such as carb cleaner).
Have any of you used it? Is it any good?
