CRC Contact Cleaner and Protectant, 10 Wt Oz, Cleans Away Contaminants, Inhibits Corrosion by Leaving a Fine, Aerosol Spray (Pack of 1)

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.

Works great for cleaning rail sliding contacts

Like most c r c products it was quality. It seemed to clean Contacts well and left a protective residue.

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.

Good stuff

Does as advertised

I've just started using this contact cleaner, but already it's solved a number of problems for me: garage door motor connections, computer USB ports, phone charging ports, etc., and any number of battery compartment contacts. Highly recommended.
