Engine bay detailed by A1 Auto Detailing

An Engine Bay cleaning/ detail can be intimidating for some people. People are skeptical about it because they're worried about getting the engine wet and cause damage to the engine. I'm going to tell you how you can detail and clean an engine bay the right way, to prevent any damage to your engine and keep it looking clean. A couple tools that you will need to detail your engine bay is a Pressure washer with low PSI or a hose, a degreaser , detail brushes , and some microfiber towels.

First step in detailing your engine is to start by removing any leaf's that might be stuck in the engine or in between the drain on the sides and the top of the engine. After you have removed all the large debris you will start covering the battery, air filter , and alternator with a plastic bag . You will also want to make sure that you cover an electrical connections that might be damaged by water. Most modern vehicle have engine bays that are waterproofed, so there is not much to cover on modern vehicles. For older vehicles you will want to make sure to cover any other important parts that might not be happy with getting water on them.

Next step is to spray your degreaser or cleaner of choice and start to scrub and clean any of the plastics and areas with a lot of grime. After this you will mist the engine bay with water to wash off the chemical and grime, but you want to make sure to wash the engine carefully and with light pressure to prevent getting water into any unwanted areas. After you have cleaned the engine bay and have felt satisficed with your detailed cleaning, you will grab some microfiber towels and start to dry up all excess water that was left up on the engine. You can even use compressed air or a leaf blower to dry up the water, but make sure to not force any water into any unwanted areas.

After this you will uncover the parts that you covered with a plastic bag and clean them up without water. Last step in the engine bay detail process is to grab your plastic protection of choice and apply it to all the plastics to keep shiny, nice, and protected from dirt and grime.
