Step-by-Step Guide to Clean Engine Bay Without Water:

Step 1: Cover Sensitive Engine Parts

Before starting your cleaning process, it’s important to cover any sensitive engine components that can be damaged by water or cleaning solutions.

You can use plastic bags to cover the alternator, spark plugs, distributor cap, and other sensitive areas.

Step 2: Remove Loose Dirt and Debris

Use a detailing brush and compressed air to blow out dirt, debris, and dust particles from the engine bay. This is very important because it will prevent dust and dirt from getting trapped in the cracks and crevices of the engine bay.

Step 3: Apply All-Purpose Cleaner

Apply the all-purpose cleaner to the engine bay by spraying it on a microfiber towel or detailing brush. Work in small sections to avoid allowing the cleaner to dry on the engine bay.

Use the detailing brush to scrub the cleaner into hard-to-reach areas. For tough stains, let the solution sit for a few minutes before wiping it off.

Step 4: Wipe Down Engine Bay

Use a clean microfiber towel to wipe away the cleaner from the engine bay. Make sure to remove all the dirt and grime from the engine bay surface.

Step 5: Apply Protectant Spray

Once you’ve wiped down the engine bay, apply protectant spray to help protect the parts from dust and dirt in the future. Spray the protectant evenly on all engine bay surfaces.

Step 6: Remove Plastic Bags

Remove the plastic bags from sensitive engine components that you covered earlier.

Step 7: Final Checkup

After completing all the steps above, do a final checkup to ensure that all areas are clean and free of dirt and debris.
