Now it’s time to actually start cleaning the engine bay. There are a handful of things you’re going to need to get this done. Those things include some water with a little bit of dish soap, some brushes, microfiber towels, and a garbage bag.
The first thing you want to do is put a garbage bag over the engine for the first step in the process. To start, what you want to do is apply some of the soapy water to the painted walls and components to the side of the engine.
Once you’ve applied the soapy water to the side of the engine bay, you can agitate it with a brush and then rinse it off with a hose set to the shower setting. When you’re done, you can dry it off.
Now, once you’re done with that you can remove the garbage bag from the engine. The reason we had it on there is to avoid getting too much water on the engine itself.
In order to clean the engine, you want to avoid using a hose entirely. To clean the engine, use the soapy water you have in the spray bottle, and spray a bit at a time on the engine. When you’ve sprayed a section of the engine, you can use a brush to agitate the grease and dirt. At that point, use a microfiber towel to remove the dirt and grease that you agitated.
Avoid using a hose or water as much as possible when cleaning the engine, because you want to prevent too much water getting onto electrical components.
Once everything has been cleaned, go over the engine bay with a microfiber towel and get rid of as much water as you can. If there is any standing water on the engine, make sure you get rid of all of that before continuing forward.
