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.

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.
