Beware Before Cleaning Your Car Engine
Nowadays, car engines have become far more complex in their functionality. Beneath the shiny hood lies a network of delicate sensors — including the common rail pressure sensor, fuel mass flow rate sensor, air flow mass rate sensor, and turbo sensor. Together, these components are quite expensive, which is why you need to be extremely cautious while cleaning.
Personally, we prefer to gently clean the outer part of the engine using a clean cloth and remove any oil leakage with diesel.
With today’s technological advancements, car engines come equipped with advanced electronic systems — and one wrong step can lead to costly damage. So, if you’re unsure or inexperienced, it’s best to avoid deep cleaning on your own. Sometimes, less truly is more when it comes to keeping your engine safe and spotless.
Here, we’re going to explain the correct way to clean your car engine. A common question people usually whether it’s safe to clean the engine with water. If you follow the right method, your engine will shine like new.one
Before cleaning the engine, make sure that the engine oil cap, windshield washer cap, and fuse box cover are properly fitted. If they aren’t sealed correctly, water may enter the engine. Most manufacturers already provide protection for the wiring and other components — just remember not to spray too much water on the car’s alternator.
Materials & Tools Needed

After applying it once, you need to apply it again. Then, leave the engine for about 5 minutes. Take one liter of water and mix detergent in it well so that it forms enough foam. Apply this foamy mixture over the diesel-based liquid that we applied earlier. Now, clean it with a cloth as far as your hand can reach, and make sure to wipe the entire area properly with the cloth
