Hard Knob Issues

Hello everyone,

A button on my OT is hard to turn.
I have saxophone valve oil.
Do you think this is a good idea?
If not, what should I use for button lubrication?

for lubricating a hard knob…

i’d use contact spray from an electronics store. don’t put any oil in there!!! contact cleaner evaporates. oil will stay in there and damage things.

Yep for contact treatment spray, (aérosol pour contact).

Contact cleaner will only work for a short moment, in the end your pot has to be replaced.
Watch out where you spray this solvent, it will damage other parts.

that really depends. if the problem is rust or dirt on the wiper it will flush it out and fix it permanently. if something is mechanically damaged you’ll have to replace it.
as long as you don’t bathe your circuit board in contact cleaner for several hours or let it creep inside your display you’ll be fine. it won’t hurt anything if used within reason.
