How To Properly Clean Your Engine Bay Without Visiting A Car Wash

share on:

A lot of us can relate to washing our cars but one part of it we find most difficult to wash is the engine bay because of the fear of causing damage. The fear of causing damage to your car is a totally understandable one as if you are not careful, water could touch some areas that will cost you a fortune to repair.

You don’t have to fret however, as we present a step by step guide that can help you wash your engine bay successfully.

Wash The Engine Bay First
Before washing other areas of your car, it is best you wash the engine bay first. There is a huge chance that water will be sprayed on the windshield, the fenders, the front grill, and close areas when you wash and if you end up doing this last, you will probably be working over the clean areas you had previously cleaned.

Ensure The Engine Is Cool
A cool engine is essential so as to prevent you from burning your hands and skin. If your engine is hot, you can choose to start working on the interior of the car first and leave the hood open to cool.

It should become cool in about 30 minutes. The Next to do is to remove trapped dirt, twigs and leaves stuck in the hood jams and fresh air vents. Use your hand or compressed air if you have any available.

Avoid using water to dislodge the junk as it will only make a globby mess of debris that drips into the holes and become more difficult to remove.

Cover Up Electrical Parts
The next thing to do is to cover up any exposed electrical parts with nylon, plastic bag or aluminum. The electrical parts that needs covering include the Alternators, air filters and fuse boxes. The essence of this is to add a bit of safety in the event that water from your hose comes in contact with the area.

Starting Your Wash
If your car happens to have an exposed dip stick, wrap some tape around it to avoid water dripping down the dip stick and into your oil reservoir. Put your water hose on wide or fan mode and lightly rinse down the engine. Add a bit of detergent to dirty areas.

Immediately afterwards, scrub using a soft brush such as a toothbrush or any toothpick type tools for any tight spots in and around the engine bay. However take note that whatever you do, never allow the detergent to dry on the engine parts.

Remember in most cases the engine is usually somewhat warm so the evaporation can be a bit quicker than you might think. As such, it is best to lightly rinse again if it is starting to dry too fast.

Now, fully rinse the detergent off, and double check for areas you may have missed. If you missed anything, repeat the same steps.

Dry With Compressed Air
Once you are sure that the dirt and grease are gone, dry your engine with compressed air using an electric blower while wiping with a used microfiber towel at the same time. If you don’t have an electric blower, you can simply make use of the towel.

Once nearly dry, remove all the plastic protection, and then continue cleaning by hand with the microfiber towel. Before proceeding, start the engine, and let it run for two to three minutes to make sure all the fuses and computer components are functioning properly while getting some heat build up in the engine to promote evaporation.

Lastly, dress the components on the engine with a water-based tire dressing. Lightly wipe the dressing down to avoid attracting dust and dirt before it dries. While engines are not the first thing people see when looking at your car, it is healthy and necessary for you to clean them at least twice a year if driven daily.
