A very small amount of this product removes carbon, dirt, and other contaminants from sliding electrical contacts, jacks, and connectors, and protects the contacts of electronic devices and other equipment from oxidation and sulfurization. Prevents and stabilizes increased contact resistance due to contact wear, thereby extending the life of contacts. Since it is a non-silicone type based on chemically stable synthetic oil, there is no concern about contact damage caused by low molecular weight siloxanes, and it does not damage most materials. There are three variations with different contents.See variations with different capacities
