For removal of oxide and sulfide films on electrical contacts

Prices have been revised effective July 1, 2023.

This is a neutral type contact revival and rust remover developed for use with precious metals used in electrical contacts of electrical and electronic equipment. It removes oxide and sulfide films adhering to contacts and restores the energizing function. Since it is a neutral type, it has extremely low corrosiveness to metals and does not damage base metals. It is also non-abrasive and will not damage the surface of the base material. It is not irritating to the human body and has excellent workability and safety. Ideal for restoring current-carrying functions when oxidation and sulfurization of contact surfaces are severe.
