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

Good stuff

Good product

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.

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

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.
