Step 2: Cool off the engine

Before cleaning the cab, the car owner should open the hood to cool down the engine. The engine chamber is often closed, which absorbs a relatively hot amount of heat, not to mention the smell of gasoline. Opening the hood will help the engine cool down, thus easier for car owners to clean without worrying about the risk of burns.

Step 3: Close the black box, battery, intake manifold

Use the black box cover, battery, intake manifold ... to avoid contamination during cleaning with dirt or cleaning solution and water leak.

Step 4: Dry clean the parts in the machine compartment

Pick up all the trash pieces, small leaves in the hard-to-reach corners of the compartment. Use a soft brush to thoroughly clean dirt and wipe oil leaks on the car hood.

Step 5: Apply from outside to inside, from top to bottom

Use sprayers on the outside and under the hood. Then remove the stains on it by clean towel. Then use a spray of mild water spray on the small parts of the machine and dry clean it.

Step 6: Spray the engine compartment with a specialized cleaning solution:

After wiping with water, the car owner should spray a specialized cleaning solution on the engine compartment. Wait for a few minutes for it to soak in the solution and use a brush and a towel to clean all the small parts.
