Engine cleaning is the process of removing dirt, grease, and grime from the engine compartment of a vehicle. This helps improve the engine's performance and longevity by preventing corrosion and overheating. Regular cleaning can also make it easier to spot potential issues, such as leaks or worn parts. There are various methods for engine cleaning, including using a pressure washer, degreasers, or steam cleaning. It's important to cover sensitive components like electrical connections and air intakes to avoid damage. Proper engine cleaning can enhance the overall appearance of the vehicle and contribute to better maintenance practices.
