Step 3: Clean the Engine

With the engine bay prepared and covered, it’s time to focus on cleaning the engine itself. Carefully remove the plastic cover from the engine to begin the cleaning process. Using cleaning wipes, remove any excess dirt, sludge, and oil stains from the valve covers and surrounding areas. Depending on the level of dirtiness, you may need to use more cleaning wipes than usual to ensure thorough cleaning.
Next, spray a liquid cleaner on the dirty areas and wipe clean with a microfiber towel. Work on one section at a time, paying close attention to nooks, crevices, and wiring sockets with thicker dirt buildup. For hard-to-reach areas, use a detailing brush to ensure a thorough cleaning. Once the cleaning is complete, use a separate dry towel to give the cleaned sections a final wipe, removing any excess moisture and preparing the engine bay for the final detailing step.
