Well its the only product I've used that has held up so far

I've been using CAIG products on audio equipment for decades and I love all of them.

Best used with Q-TIPS (cotton buds), and remove the cotton part (by cutting it off at both ends, and then only using the tube as a dropper (straw-like) instead, and then discard when done - no contamination.

This is the best oxidation remover that I have ever used.
