I haven't found a real replacement for Deoxit. Expensive, but nothing I've found works as well.
Same. Deoxit cuts crap that others won't touch.
I dealt with scratchy pots for a year because I was too frugal to buy deoxit and was convinced I could get something just as good for less. So I tried. After buying and trying some contact cleaners at the auto parts store, nothing helped. They were still just as scratchy as ever. So I dealt with it for the next year by not going all the way to 10 or 0.
Finally, one day I decided to buy deoxit to see if it really was as good as people said. I shot just a squirt into the pots, worked em back and forth and the crackling and popping and scratching was gone. After a single application.
I'm a firm believer in Deoxit these days.
