Caig Deoxit Gold G100L-P6C Pen 6ml

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, etc.).
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/oxidised, preclean with DeoxIT D5.
DeoxIT Gold is designed to dissolve small amounts of oxidation. 

100% solution, no solvents
