Contact Cleaner is a chemical spray designed to clean and improve the conductivity of electrical contacts.

Over time, the metal contacts of plugs, jacks, knobs, and faders can oxidize or accumulate dirt and dust. This contamination creates electrical resistance, resulting in poor contact, noise (hissing and popping), or even total signal interruption.

Contact cleaner dissolves and removes this oxidation and dirt, restoring a clean and reliable electrical connection between parts. It is an essential tool for maintaining audio equipment, used to troubleshoot connectors, potentiometers, and switches.
