How To Clean Your Car’s Engine Safely

Avandacar – If you love your car, then you must want it to be clean. When talking about cleanliness, it's not only the exterior but also the interior, including the part under the hood, the engine. Even though the engine is not directly exposed to the outside environment, dust and debris still can sneak through the small openings around the hood and the front end of your car.

But cleaning your engine is not as easy and simple as washing the exterior of your car. This chore may sound daunting, but if you know what you're doing, then it's quite simple. Here are several steps you should take in safely and efficiently.

Schedule and Prepare

Next, you need to prepare your car. Make sure your car is completely cool down before you clean your engine. If you just came home, wait for at least 15 minutes before you start to clean.

If you're not sure, you could also remove the battery altogether even though this is not necessary.

Cover Delicate Parts
