Engine cleaning – products for washing the engine bay

Dust, greasy deposits and road grime build up in the engine bay. Engine-cleaning products can help remove dirt from suitable surfaces, but care is needed around wiring, electrical connectors and sensitive components. This category includes spray cleaners and larger workshop packs.

What should you use to clean a car engine?

First check whether the product is suitable for the specific material, such as aluminium, painted metal or plastic. Follow dilution and rinsing instructions. Uncontrolled use of aggressive detergents can damage coatings and electrical components.

How to clean an engine bay safely

1. Work with the engine switched off and cooled down.
2. Protect components specified by the vehicle manufacturer, especially sensitive connectors and air intakes.
3. Remove loose dirt and apply the cleaner as directed.
4. Avoid directing high-pressure water at electrical systems.
5. Thoroughly remove cleaner residues and dry surfaces before starting the vehicle.

Will cleaning fix an oil leak?

A cleaner may remove greasy deposits but cannot repair a leaking gasket, hose or other source of a leak. If the dirt returns quickly, diagnosis is needed. For serious leaks or flooded electrical components, consult a workshop.
