Why shouldn’t I use washing up liquid on my vehicle?

When added to hot water, washing up liquid is designed to cut through grease so, obviously, it can also strip away any protective layers from your vehicle, leaving it exposed to the elements and liable to rust. On the other hand, with its gentle formula, Mer Super Advanced Shampoo is considered one of the best on the market.

Washing up liquids also contain salt which will start the rusting process on any exposed metalwork caused by problems such as stone chips and scratches.

As a general rule, it’s best not to use household products on your car – although much of the Mer range works well for the home, particularly Mer Carpet & Upholstery Cleaner, Mer Leather Cleaner and Mer Rapid Spray Glass Cleaner.  Mer Ultimate Polish is also ideal to use on uPVC windows.m.
