DeoxIT ® Power Booster 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 with severe oxidation and corrosion. If the metal surface is discolored, it is severe. DeoxIT ® dissolves the contamination and protects the surface. For reference, DeoxIT ® has approximately 20% cleaning action.
