How to Wash Engine at Car Wash

Step 1: Prepare the Car

• Park the car in a well-ventilated area.
• Turn off the engine and allow it to cool down.
• Disconnect the battery negative terminal.
• Cover the alternator, distributor, and other electrical components with plastic bags.

Step 2: Apply Degreaser

• Apply a commercial engine degreaser to the engine and surrounding areas.
• Allow the degreaser to sit for the recommended time, typically 10-15 minutes.
• Use a soft-bristled brush to gently agitate the degreaser.

Step 3: Rinse the Engine

• Use a high-pressure washer to rinse the engine and surrounding areas thoroughly.
• Start at a low pressure and gradually increase it.
• Avoid spraying water directly into electrical components.

Step 4: Dry the Engine

• Use a clean, dry towel to absorb excess water from the engine.
• Start the engine and let it run for a few minutes to help dry it completely.
• Reconnect the battery negative terminal.

Step 5: Protect the Engine

• Apply a thin layer of engine protectant spray to prevent corrosion and rust.
• Allow the protectant to dry completely before driving the car.

Tips for Washing an Engine

• Wear gloves and eye protection when using degreaser and high-pressure washer.
• Avoid using harsh detergents or solvents.
• If the engine is particularly dirty, consider using a steam cleaner.
• Wash the engine regularly, especially after driving in dusty or muddy conditions.
• Do not wash the engine if it is still hot.
