Würth electrical contact cleaner, 500 ml — a fast-evaporating spray for cleaning switches, relays, connectors, circuit boards and motor contacts.
It removes oil, dust and light oxidation and dries without leaving a film, so it will not attract dust or bridge a contact afterwards. A very common fix for an intermittent switch or a connector that has gone high-resistance.
Isolate the circuit before spraying and let the part dry completely before powering up. We also stock WD-40 contact cleaner.
Stocked at WPL Trading, No. 305, Kandy Road, Warakapola, with island-wide delivery. Call +94 71 302 4843.
