Cleaning car’s engine is important to keep it operating at its best. That is why you need to keep it in good shape all the time. You need to clean it regularly to avoid damage that can affect engine operation.

Remember that in doing engine cleaning you need to have a good place to work it. This should not be done in your yard. The grease and the degreaser are harmful to the environment and will kill your grass.

The things you need when doing engine cleaning: engine degreaser, water, and rags

The first thing you need to do is to protect the electrical parts. Cover the distributor with plastic because this part is usually having wires coming off it and going to the spark plugs. There are some vehicles with no wires because they have a coil sitting on top of each spark plug. You need to cover these parts because if this gets wet, you will not be able to start your car for quite a while. You may even short the computer. Also you need to cover the sensors. You may not be able to find them all, but many of the sensors are not bothered by a little water. The sensors MAP or MAF located in the air intake should also be protected from water.

After covering the electrical parts, you can now spray the walls of the engine compartment and the bottom of the block with an engine degreaser. Then when you are rinsing the compartment, you need to do it carefully. Do not splash water on the top of the engine. Again with the use of a degreaser sprayed on the rag, start going over the top parts of the engine. You might have to scrub vigorously, depending on the amount of grease. But the top of the engine is normally just grimed up with dust and dirt and should easily come clean.

After you applied ample amount of degreaser on the engine parts, use a clean rag, soak it and squeeze out excess water. Don’t forget to wipe up the degreaser from the previous step. If you still have a lot of grease on your engine, go over the steps again. You can scrub some spots with stubborn grease again and again until such time that it is completely gone. You may use an abrasive sponge, but be careful not to scratch your engine. Warning: Do not use abrasives on chrome.

Then the last thing you need to do is to inspect the engine assembly if there are spots which needs to be cleaned; carefully remove the covers in the electrical parts. You need to test you engine after cleaning it. See the difference of a clean engine when operating. You’ll surely experience great performance!
