What contact cleaner do you recommend?


Have read very positive claims regarding Extreme SST by Walker Audio. My main concern is possible damage to your components? Is this a valid concern? Are there better more effective(safe) contact cleaners/paste available. All comments are much appreciated.

Thanx for the suggestions. The Kontak appears to be what i'm looking for. The Stabilant 22 is more lubricant then cleaner. Has anyone used Kontak on tube pins? If so were the results positive?

Good advice Elizabeth. I too use Caig very lightly about only once year but am happy with the results. Also use it on my guitar amps, pots and connections too.
Tweek. Excellent example of a contact enhancer that does degrade over time. It turns a dark greenish black. By contrast, Cramolin Red, the one used in aircraft communications electronics, works great and does not degrade over time.
i just thought of another solvent that could be considered,namely, cramolin.
