An electrical contact connection is all too often overlooked as a weak link in many vehicles. The sheer combination of damp conditions or even water and general grime with electrics and the metal connectors that are regularly used are simply a recipe for failure.

A failure can often prove frustrating, a nuisance and expensive – not to mention the difference in a MOT pass or failure. Crucially, it’s one that can often be avoided!

Lights are the primary problematic area. While many motorists may reach out to their nearest auto store when their lights flicker or fail, the root of the problem may be simple to rectify. In the case of Zenon bulbs, which are an expensive replacement, it could well be the contact within the plastic-coated and easily recognisable mechanism clip that causes the problem.

Within an engine bay, even the un-trained eye will spot numerous plastic-coated connectors which seem to be pretty exposed. Typical is the connector for an air mass sensor which, if faulty, can seriously prevent an engine from running smoothly and efficiently. Incredibly, the connector is often just loose and totally exposed to day-to-day grime.

The first port of call for any technical help would be to disconnect the battery and then unclip/pull apart a connector – and that’s where a simple blast of WD-40®’s Fast Drying Contact Cleaner found within its array of Specialist products comes into its own.

Completely safe but, as with every WD-40® product, highly and almost instantly effective, the fast-acting and non-conductive solution penetrates the area and leaves no residue. While primarily developed for electrical equipment, it is regularly and safe to use on rubber and plastic items.
