Engine washing is an important stage of maintenance, since during operation, dirt gets into the space under the hood and over time this leads to corrosion and failure of the main components of the car's chassis. There are several ways to wash the engine: dry cleaning, steam washing, high pressure washing, and low pressure washing. Dry cleaning involves the use of specific products that cover the engine and then wipe off the dirt. Steam washing is also a dry method and is carried out using a special steam generator. High pressure washing is a potentially unsafe method, but in some cases it is also used. Low pressure washing is one of the most popular engine washing methods that implies the application of detergents to the engine and their rinsing together with dirt.
