Frequently Asked Questions

Can you clean relay contacts?

Yes, relay contacts can and should be cleaned regularly to maintain reliable electrical performance. Aerosol contact cleaners like ZL98 or Z99 are ideal — they flush away oil, grease, dust, and oxidation without leaving residue. Their non-conductive, self-evaporating formulas make them safe to use on energized relay assemblies in industrial and commercial settings.
