I saw a recent recommendation to clean amp jacks for intermittent fade issues. What method do you guys use... Spray right in the jack or onto a plug and insert or what? And which deoxit (Or alternatives) ... The 5% spray? Thanks!
My trick for dirty jacks is to first safely remove them, and then just put a new one back in.
But for real, 99% of the time giving a small spray into the Jack will be just fine. But there is also a chance it won’t so be careful.
Make sure the jack is screwed in tight too. Sometimes when they are loose they spin a little and depending how tightly the wires are run it could be stressing the solder joints
Deoxit makes a Fader Lube that's good for pots. Dielectric grease is the best but it's pretty tough to get that back in there without removing the pot casing.
