Ya know, on/off switches with (presumably) membrane contacts beneath?

I dug out my old Focusrite Twin Trak Pro and some of the buttons are so scratchy they short in and out with just a gentle touch.

I'm reluctant to try anything with a propellant.

Try pressing them a bunch of times to break up any oxidation that's in there.


As long as it's working I wouldn't worry about it.

Yeah, I did that initially and it helped some, but the monitor/mute button is really hinky. Sometimes it has a hum in the right channel which a little flick can make go away. But...

My concern is if would play nice with the membrane beneath or dissolve it.

Membrane switches are theoretically the easiest to clean.

If you can remove the membrane all the better.

I doubt a product designed for cleaning contacts would dissolve it.

Maybe try some canned or compressed air first.

A drop of isopropyl alcohol on a microfiber cloth or foam swab and a few wipes of the PC board and the bottom of the button (carbon contact surface) will clean it perfectly.

If you use a cotton swab, carefully inspect after cleaning to ensure there are no fibers remaining.

I've been having good luck with pipe cleaners lately using alcohol for cleaning. I fold three of them in half and then stack them into one unit for 1/4 inch jacks . Four seems to cause problems getting stuck so three work well. There are a couple different types. I use the ones with a plastic "scrubber" on it. These seem to let you scrub a bit to remove any varnish, smoke, or other sticky substance. Works well on all the jacks mono,trs, as well as switching jacks. They seem to open the switching part as they go in letting whatever cleaner used get access to the normally closed contacts.
Works great on tube sockets as well as those tiny midi ins as well.
They normally don't leave anything behind, inexpensive and let you even get rust off of old contacts. After wards a bit of fader lube helps on the rusty ones.

The buttons seem to respond well to pipe cleaners as well if you can access the contacts.
