Did a good job of cleaning radio frequency switches and some potentiometers. Back in the late 60s, early 70s I worked my way through college and grad school in a GE owned TV, stereo repair shop. Numerous control and contact cleaners were available then which are not on the market now. This works better than the others I've tried recently and seems up to par with the better ones from my past.
