DeoxIT is a fast-acting deoxidizing solution that cleans, preserves, lubricates and improves conductivity on all metal connectors and contacts. Use on general contact surfaces and other metal surfaces, and on non-critical metal surfaces with severe oxidation and corrosion. If the metal surface is discolored, the corrosion is severe. DeoxIT dissolves the contamination and protects the surface. Not only does DeoxIT remove corrosion but it also seals and protects all electrical connections, and reduces intermittent failures, arcing, wear, and abrasion. Temperature range: -34 ° C to 200 ° C. 7.4 mL, 100% DeoxIT concentrate. Includes brush applicator. Non-flammable, non-toxic.
