Engine Bay Cleaning

Engine bay cleaning removes oil, dust and dirt from under the bonnet, making leaks easier to spot and the car easier to work on.

What is Engine Bay Cleaning?

It is often done with a degreaser and soft brushes. Sensitive parts are covered before rinsing. A clean engine bay helps when selling a car. After cleaning, plastic dressing can protect hoses and covers.

How it works

Degreasers loosen oily dirt, which is then wiped or gently rinsed away.

Why it matters for your car

Do not aim a pressure washer at connectors, fuse boxes or the alternator. Clean a cool engine and let it dry before starting.
