Caig Labs ProGold G5 Contact Cleaner

While standard cleaners simply remove dirt and residue, the ProGold G5 also leaves behind a protective lubricant. This layer helps prevent future corrosion and fretting while actively enhancing conductivity.

It is designed for metal-to-metal contacts, such as connectors, switches, and potentiometers. Avoid using it on plastic-only surfaces or components where the lubricant might attract dust or interfere with mechanical movement.

For most applications, a light spray is sufficient. If you accidentally overspray, you can gently wipe away the excess with a lint-free cloth to prevent the lubricant from pooling.

Yes, it is highly effective for that purpose. By cleaning the internal contacts and providing a thin layer of lubrication, it can often eliminate the noise caused by oxidation and wear.

The longevity depends on the environment and how often the connection is moved. In most indoor electronic applications, the protective coating remains effective for a significant period, though high-wear components may require occasional reapplication.
