Contact Cleaner – 05018

Electrical contact cleaner strips oxidation, dust, and oily residue off switch contacts, connectors, and terminals, restoring a clean conductive surface so the connection carries current without the added resistance that fouled contacts introduce. It flushes the contact and flashes off fast, leaving no film behind, so the circuit goes back into service clean and dry rather than sticky or coated.

Dirty and corroded contacts are behind a large share of intermittent electrical faults and voltage drop, and a thorough cleaning is often the actual fix, the step worth taking before a switch, relay, or connector gets condemned and replaced. Restoring the contact surface can bring a circuit back without a parts swap at all.

Sold by the case of twelve cans, it suits a shop keeping electrical connections clean across a whole fleet rather than treating one connection at a time, so the cleaner is on the shelf whenever a faulty connection turns up.
