Seemed to be in pretty good shape, but it was a little dirty and the volume knob had a lot of static in it - when turning the volume up and down, there was a lot of scratchy noise, and sometimes one of the channels would cut out a bit

No scratchy noise when adjusting volume, balance, source, etc

It worked great in my audio equipments fantastic, no more scratchy noise from my equalizer's sliders and from my power amp's control

I've used it on my iPhone power button (which would randomly not work), a motherboard, a guitar pedal (which was making scratchy noises), the cord plug receiver in my Les Paul (which was also not making good, positive contact, and making scratchy noises) and quite a few other things... and they all work fine now... simply amazing stuff

My Fender Hot Rod Deluxe was making all sorts of static and microphonic noises, even with new tubes

I sprayed the switches and knobs on my guitars and basses and it got rid of the nasty gritty noises

The best contact, and pot cleaner made I use it on all my guitars and amps when the pots get scratchy, one or two sprays and bye bye scratchy noises..hello quiet pots and switches

It hasn't cleared up the noise in the pot in my guitar after two tries

This product has cleared up numerous issues with sticky stereo knobs and that terrible crackling noise you get from some of the controls

my god the sound at that hour all nasty noises gone

I had some noise and the switch was not working properly but now it is as good as new.

Seems to have done the job and cleaned up the noise in the volume control

Volume control on stereo receiver making weird noises - spray in volume control, and rotate it back and forth a few times.3

Completely eliminated the scratchy noise when actuating these control keys.

The volume knob had started to make a loud crackling noise whenever the volume was adjusted, and a friend suggested I try Deoxit

It really does work and gets rid of the static noise you get when you turn your volume control on your radio or guitar for example.

Further, until at least a solid half hour to 45 minutes went by, the tuner functioned wildly and sometimes would not budge at all in frequency read-out(s) or, worse, suddenly render a totally out of band frequency
