Protect ConnectionsDeoxIT® GOLD (formerly ProGold), is a unique conditioning solution that improves conductivity and provides long-lasting protection on gold, base metals and other precious metal contacts and connections (gold, silver, rhodium, copper, bronze, nickel, etc.). Use on plated connectors, contacts and metal surfaces for maximum performance and protection. Recommended for critical applications where only slight cleaning action is necessary. If the surface looks clean, applying DeoxIT contact cleaner first is usually not necessary. DeoxIT® GOLD is designed to dissolve small amounts of oxidation. Apply DeoxIT® GOLD after DeoxIT® contact cleaner on plated metal surfaces, except where noted with DeoxIT® SHIELD below. The more critical the connection or part, especially low current applications, DeoxIT® GOLD should be the final step. For reference, DeoxIT® GOLD has approximately 0.5% cleaning action.
