I tried to use it one to clean a dirty volume pot in an older TV.
It worked great,for about 3 minutes,then the volume control was
stiff,and sticky

I haven't had any problems. I've been using it to clean pots since tuner
cleaner turned to crap when it went CFC free. When was that? about 1990? I'm in
the business and have cleaned many thousand controls with WD40 and it works
great.
