How to Clean Your Car’s Engine Safely

Washing is a crucial part of car maintenance, but cleaning the engine is a hassle. Grime and dirt gather under the hood, and dust creeps into the openings. Cleaning the power unit requires caution, as there are many electrical elements. Follow our tips to do it properly.

The Best Time

Experts recommend washing the engine in warm temperatures. Combined with low humidity, they create the best conditions, whether you use a degreaser or an auto detail steam cleaner. The wind will also help the power unit dry more quickly. Here are the main stages of DIY wash.

Prepare for Washing

Allow the engine to cool down if your vehicle has been running recently. Open the hood. Wait to avoid getting burned. Spaying a hot engine with a hose or a steam cleaner for cars may also cause rapid contraction. Car owners who use a steam machine for car detailing need to wait for at least two hours. 

Any plastic covers must be cleaned separately, so take them out. To protect the electrical components, remove the negative terminal, too. Otherwise, they will get wet. It is not necessary to take out the whole battery. 

All electronic components are very sensitive to moisture. This includes your battery, engine control unit, and ignition wires. They should be protected, so cover them with plastic bags. Cover the engine air intake if it is exposed and you are not sure you will be careful when rinsing. This is crucial if you will use a car detailing steamer, too. 

Degreasing the Engine

Use a special spray to degrease the whole engine compartment. Even a household degreaser will do. Be thorough and cover every inch. A steamer may cope with cleaning without degreasing, or you may need to spray only stubborn areas. 

Scrubbing the Engine

Use a small brush to clean away any caked-on dirt. Its bristles should be synthetic, but not metallic to avoid damage. If your engine is not too dirty, you may skip this step. Scrubbing is only necessary for gunk in areas like the valve cover. 

Rinsing and Drying

You can rinse the degreaser off with a standard hose. If you use a power washer, use the light mode. Rinse thoroughly, starting from the back of the compartment. Avoid electrical parts and do not spray too much in areas that do not dry quickly.

Wipe all the components with a rag or shop towel. To speed up drying, use compressed air. Direct it in crannies and nooks to drive the water away. Finally, reinstall the negative terminal and remove the plastic bags. 

Steam Cleaning the Engine

In recent years, auto detailing steamers have been gaining popularity. These services allow you to get rid of dirt and gunk in the engine in a sustainable way. No chemicals are used, and the amount of water is minimal. Manufacturers like Fortador offer universal steamers that can be used for the interior and exterior. This is an effective and eco-friendly way to keep your vehicle clean.
