DeoxIT - Contact Cleaner and Rejuvenator
DeoxIT Contact Cleaner is a fast-acting deoxidizing solution that cleans, preserves, lubricates and improves conductivity on all metal connectors and contacts.
Use as a general treatment for connectors, contacts and other metal surfaces and on non-critical metal surfaces exhibiting severe oxidation and corrosion. (If the metal surface is discolored, it's serious.) DeoxIT dissolves contamination and protects the surface. For reference, DeoxIT has a cleaning action of around 20%.
