Are you wondering how to safely clean a car engine? We found out—check out the step-by-step process below.
- Clean off loose debris. Leaves, dust, etc. accumulate in your car's engine area over time. Use an old paint brush or leaf blower to get loose debris off the engine.
- Start the engine. Allow the engine to run for a few minutes to slightly warm up. The engine should be slightly warm to touch, not hot. Your cleaner will not work well if your engine is too hot.
- Use foil to cover the air intake. Also use foil to cover the alternator and exposed filters.
- Use a degreaser or citrus cleaner. Use the cleaner of choice sparingly. Spray a small amount on engine parts, not on a rag or sponge. Degreaser will remove wax. These products can be found in any mart or drug store.
- Start by cleaning the perimeter of the engine bay. Next move on to the hoses and fluid containers. Use a mitt or brush for hard to clean areas. Rinse with a slow stream of water.
- Spray the firewall. Spray down as far as possible to eliminate dust, dirt and grease.
- Use your detail brush or wash mitt to continue cleaning in tighter areas of the perimeter. These supplies can be purchased inexpensively at any auto store or mart store.
- Move cleaning inward toward the middle of the engine. Continue using your mitt or brush with a bit of effort to remove grease and grime.
- Dry the engine. Use rags to dry the areas that were just degreased. Make sure the area is completely dry if following up with a wax. Waxing is optional. Do not use carnauba based wax.
