Enthusiasts often fear to detail engines bay simply because they don’t know the process of how to do it, and afraid of damaging the engine. You can wash and detail your engine without much concern of damaging anything. Does not over spray the engine with cleaners, degreasers, and Do not over spray water or a high pressure washer. Engine detailing takes a bit more effort to do a good job.


      Precautions to be taken -

Never detail a hot engine. Wait till the engine cools. The best time to detail your engine is in the morning when it has been shut off all night. If you Use cold water on a hot engine then you have higher risk of causing damage or cracking cover, casing or some time makes parts brittle. M sure the engine is cool before you start work. Some Experts advice to warm up the engine as it helps to loosen the stains and grease buy if you do so make sure it’s just warm and not hot, Cleaners & Degreasers when sprayed on hot surface will dry and leave stains, ultimately you make more work for yourself.



Before you begin to clean using cleaners or begin to detail engine, cover the Motors, motor coil, alternator, Air filters, and the engine's air intake. These are the areas which should be kept far away from water as much as possible. Cover theses with a bag, and then be sure to remove the bag after you are done with your Job. These precautions are required only on old engines which are open, Modern design Engine are sealed and covered so the risk is low and details is quick due to covered surface.



 You might also want to consider any other areas of the engine that might need to stay away from water. If you have done any custom work then you may have electrical connections, cutout, fuse or gauges that you want to cover. Just be alert on which areas to keep away from water. You can always hand clean those areas after you get the rest of the dirt out. Remember: Use low level water and cleaners as needed to get the job done.

         Cleaning the First Layer Dirt and Grease


Start with spraying degreaser or engine cleaner as these are intense degreaser that works well on greasy engines. Spray the cleaner on all possible areas you can see and look for small areas which have chances of accumulating grease and dirt, this activity of finding the spots to clean decides the overall outcome of the effort.  To get the degreaser off you simply need to rinse it with a slow stream of water, or if low steam water is not available then use regular water with regular hose. You can use your thumb over the tip of the hose to create a little pressure, but for the most part, degreaser will do the work and get cut the dirt. Anything that is tough to go, wipe with hand or soft cloth.


After above Step ,which loosens the stain or grease, there will be still most stuff left behind, what does not go with light hose pressure , it is best to clean using hand and special tools designated for engine detailing, like gloves, engine detailing brush, mitt etc. Keep a separate set of kit or tools exclusively for engine compartment and use new tools for detailing other parts of car. For far of reach areas which are not reachable by hand use long bristle brushes, flexible and spring brushes to clean thoroughly, this flexible brush are chemical resistant and are of excellent use to detail like professional. The brush is 17 inches long overall and the bristles are 2 inch long for large brush and 12 inch Long brush has 1 inch Bristle. Always use soft bristled brushes and never use brass or stainless steel ones. Those will scratch plastic and paint makes it all look ugly.


       Second Level Check –


Wash the engine and make sure that all the dirt is gone. You can wet the mitt with All-purpose cleaner to create foam or sometimes some people use the regular car wash shampoo to create the Foam using Mitt. Use Brush to clean hard stain area, and areas where hand is unable to reach to clear sticky stains.




Or you may need to mix some soapy water in a spray bottle to assist in your detailing. That helps get the areas that need more attention. Just have some regular cleaning towels to wipe off the activity while you spray and brush. We recommend you to have few microfiber towels for engine detailing. You can use your old towels for engine cleaning as well

Finish the Job with a Gloss -

The engine needs to be dried before proceeding with wax or protectants. After you have cleaned and dried the engine, look for areas of improvement, when all looks fine in terms of cleaning then it’s time to put some glow for the engine.

You can actually wax the paint if you want to, but use a high quality sealant as wax will wipe off when engine heats up and runs some miles. The wax on engine will not last very long. 

 To shine up the plastics, Belt and hoses you can use a quality rubber/vinyl protectant or plastic Guards. Spray the Dresser and let it settle on the surface for few minutes, after it settles Wipe down the excess spray and over spray areas, on hoses and all plastic surfaces to make sure they are just as required as over spray will lead to streak mark when engine warms up.



Corrective and Preventive Measures -

Your engine will look so much better if you take a few minutes and clean it up regularly.  As Engine compartment is always lubricated with grease and oil by mechanics as it’s the basic need and Engine often goes to high and low temperature cycle and in this process the dust, tree fall and grease also gets seasoned from high to low, and low to high temperature which will only make them stick firmly on the Engine parts and engine cover.
