How to Clean a Car Engine?

After the engine has cooled down, cover the battery with plastic sheeting to prevent cleaning agents or water from damaging the electrodes during the cleaning process. The surface dust is most noticeable, and there is a significant amount of grease under the decorative cover. Only by removing it can the components underneath be cleaned. For areas with thick grease buildup, spray cleaning agent and scrub with a brush to quickly disperse the grease. Five minutes after applying the cleaning agent, wipe it off with a towel. For parts where the grease hasn't dispersed, repeat the cleaning process several times until they are satisfactorily clean.
When cleaning the engine, safety comes first to avoid water damage and malfunctions. My experience is to let the engine cool down completely—waiting about two hours after parking should suffice. Then, wear gloves to protect your hands and spray an engine-specific cleaner on heavily soiled areas, letting it soak for five minutes. Next, gently scrub the dirt with a stiff brush, being careful to avoid electronic components like sensors and spark plugs. After brushing, don’t rinse immediately—wipe it clean with a damp cloth first, or use a low-pressure water spray from a distance but dry it quickly. Finally, wipe the engine compartment with a clean towel and let it air-dry naturally for extra safety. Stay diligent by cleaning it once or twice a year to prevent carbon buildup and corrosion, extending the engine’s lifespan and saving on repair costs—both economical and hassle-free.
