The best way to clean your car's engine is to use a combination of water and mild dish soap. Make sure you are using an appropriate amount of detergent, as too much can be harmful to the engine. Use a spray bottle or cloth to apply the solution and then scrub gently with a soft-bristled brush. Rinse off any excess soap and dry the engine thoroughly before starting it up again.
