What You’ll Need

Steps to Clean Your Engine Bay

Preparing Your Engine

  • Cool Down: Ensure your engine is cool to the touch before starting. A warm engine is okay as it can help loosen dirt, but it shouldn’t be hot.
  • Remove Loose Debris: Remove any leaves, twigs, or visible debris by hand or with compressed air.
  • Cover Sensitive Areas: Use plastic bags and tape to cover electrical components, including the battery, ignition wires, and engine control unit.

Applying Degreaser

  • Spray Degreaser: Apply a liberal amount of engine degreaser from the bottom up to avoid streaking. Focus on greasy areas but avoid direct application on sensitive components.
  • Let It Sit: Allow the degreaser to work according to the product instructions, typically around 3-5 minutes.

Scrubbing

Use various sizes of soft brushes to scrub the engine bay gently. Reach different areas without applying excessive force which might displace or damage components.

Rinsing

Use a hose or a pressure washer set to a low pressure to rinse the engine bay thoroughly. Ensure all soap and degreaser are washed away.

Drying and Finishing Up

  • Dry: Use microfiber cloths to dry accessible areas. Compressed air can be used to blow out water in tight spaces.
  • Remove Covers: Take off all plastic coverings from the electrical components.
  • Final Wipe: Give everything a final wipe and check for any areas that might need a touch-up.
