This is perfect for potentiometers (pots) on electronics AFTER you have already cleaned them with DeoxIT D5. This product will lube up the moving parts to keep them working smoothly. I used this (and D5) on a used Marshall JCM900 that my guitarist bought. He got it for a great price because all of the volume and tone controls would make a crackly noise through the speakers when you would turn them. Well, I took the amp apart and hit all of the pots with D5; after they were dry I sprayed them with this F5 and now the amp's controls are dead silent! The D5 is what stopped the crackly sound but this F5 is what is gonna help them stay that way.
