Keep your car clean

Washing your car is not just about appearances: it can extend your vehicle's life.

First rinse off surface dirt> Then wash using a car shampoo. Don't use household detergent, which can corrode the paintwork. Clear drain holes and guttering of debris. Considers investing in a pressure washer to reach undesired and wheel arches. Dry off with a towel or chamois. Don't wash your car when it's hot or the water may just evaporate leaving marks.

Two to four times a year, apply a wax after washing. This adds a barrier to keep water out.

If there's no handy water supply (or you just want to save water) look for products that clean and polish one go, without water.
