CRC CLEANER

Worked well to clean corroded automotive contacts. It also helps to protect some trailer connectors exposed to weather. Easy to use with the thin straw it comes with.

Makes for cleaning track a breeze and trains actually run longer between cleanings.. pretty awesome stuff !!!

Fixed a 5-way pickup switch on an electric guitar that was only usable in a couple of positions before and had been cutting out. Sprayed into the front opening of the switch and switched it back and forth to all positions. Fixed to be like new. Sprayed an amp clean/distortion switch that was pretty much totally dead and fixed that too. Did the same thing to another amp that had some issues. So far it's kind of miraculous. Will it last? I'll try to remember to update this review if not. Update: I just fixed a very old multimeter that had a rotary switch that finally gave up. Yep, it's as good as new, and it's probably 30 years old. I did have to pull one amp apart to get to one switch. Not CRC's fault.

Made a very noticeable difference on contact points that I couldn't get to with a wire brush.

Easy to use spray to protect wiring connectors exposed to the weather. It's much less expensive than another popular brand. I use it for my travel trailer power connector and towing connector. A must have. It's supposed to prevent poor, high resistance connections, which often causes connectors to overheat.
