DeoxIT® Gold G-Series, 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 and more.). It is the only product that actually penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces. Recommended for critical applications where only slight cleaning action is necessary. If the surface looks dirty or oxidized, pre-clean with DeoxIT® D-Series contact cleaner. DeoxIT® gold is designed to dissolve small amounts of oxidation.
