How To Clean Engine Bay Right Way

The first thing to keep in mind, when cleaning an engine bay area, is to be very delicate. Otherwise, you might just cost yourself a large bill to repair it fully. There are many such horror stories described online. One can easily damage the internal wiring, comprising of all the electrical components if the person doesn’t proceed with caution. Still, cleaning your engine bay area means you get a good looking engine under the hood, and as well as the sale price of the car being increased – all these at just some easy steps.

Many people do like to use water for cleaning. But water may damage some internal electrical components, so it is not at all advised to use water for the cleaning purpose. Following is the right method to clean an engine bay, without using any kind of water.

  • Firstly, Make Preparations For The Engine: When the engine is not running, and is cold, it is recommended to remove every bit of debris from the engine surface. Then you should try to cover up that engine and other parts that are delicate, via something that will protect them. These delicate parts include intakes for air, various car sensors, wires and coils for ignition, etc.
  • Start Removing Any Kind Of Baked Dirt: Baked dirt means the dirt which gets heated up by the heat of the engine, when the engine is running. In order to remove dirt like this, it is recommended to use just a wired brush and start removing that tough dirt.
  • Then Start Applying Degreaser: It is then recommended to use any kind of engine degreaser. Some of the best ones are already mentioned above, so you can select any one of them. Spray the degreaser on the surface, and let it settle for at least 30 seconds. Also use the wired brush, so that the degreaser acts upon that tough dirt, that was mentioned earlier.
  • Start Drying The Cleaner: After you’ve done scrubbing of the degreaser with the wired brush, make sure to wipe it off with a towel that is made out of microfiber. This will make the engine surface clean now, off all dirt, and ready for applying any extra kind of engine bay detailing products. It is also recommended to make sure that there are no leftovers of degreaser under any compartment that is hidden or has wires too. That might damage the internal components and wiring.
  • Try Increasing The Shine And Help Protect The Engine: After cleaning, this is undoubtedly the perfect time to apply any detailing products, to add shine to your engine. The best way to apply is to use the detailing agent on the towel made up of microfiber and then using it to apply on the engine. This will avoid getting any kind of abrasive marks on the engine surface and will protect the engine and keep it shining for a longer time.

You should also know that, if you had used water-based methods, then you would have to use a pressure washer, so that it will help the degreaser to spread, thereby making the most impact. It is also advised to not use the spray on areas where you covered the engine delicate parts. A thing to remember though, without using and with using water will result in the same outcome. Just that, you’ll be adding more risk to your process of cleaning, by using water.


It can be easily seen that how much of an impact, these engine bay cleaners can have on our engine cleaning process. They make the process much easier and faster, and still keep the whole process, safe to perform. It is advised to get a good cleaner, preferably from the above list, and use that, instead of using any kind of regular water. Because regular water can prove to be very costly afterward. That’s why take steps from the first only.

Also, another thing to keep in mind is the use of engine detailing products too. Only suing cleaners will not do the job. Using detailing kits will help you keep that clean shine for a longer period of time so that you have to clean your engine very often. It will protect the engine surface from getting faded and also minimize any dust or grease build up. Definitely recommended besides using normal degreasers or cleaners.
