How to Clean an Aluminum Alloy Motor

Aluminum is not as hard as steel. Compared to steel, aluminum alloy is much less susceptible to rust; however, it is sensitive to chemical reactions. It may form a light coating of corrosion caused by oxidation following the use of harsh degreasers. This results in the need for arduous polishing of engine parts. To prevent this, a detailer should use a mixture of water and a soap degreaser in place of chemical solvents when cleaning aluminum alloy motors.

Instructions

Clean the Motor

1

Fill the spray bottle with soap degreaser and water per the product directions.

2

Run the engine for about 30 seconds. It should be slightly warm.

3

Spray the water and degreaser mixture onto the motor, engine components and underside of the hood. Wait one to two minutes to allow the soap degreaser to soak in.

4

Use the pressure washer to spray the underside of the hood, motor and motor components. Avoid spraying water directly on electrical components.

5

Spray soap degreaser on any remaining dirty spots. Scrub stubborn grime with the toothbrush.

6

Rinse the engine with the water hose.

7

Dry the motor, wires and other components with shop towels or rags. Finish drying by starting the motor.
