Grease, dirt, and contaminating oils accumulate on parts' surfaces as a result of the manufacturing process or road use. Just like other types of industrial parts, unfinished automotive parts must be cleansed of contaminants before they can undergo surface finishing or assembly; contaminated parts pose a hazard to equipment functionality and safety.
Automotive parts washers are necessary because normally operating vehicle engines become dirty after years of operation; spent oils require replacement, poor-quality fuel can cause build-up in engines and other products of combustion build up on engine components over time. In addition to this build-up, vehicle engine components are exposed to a wide variety of contaminants while on the road, and these can contribute to energy inefficiency and degradation of function.
When a vehicle's owner notices the vehicle's decreased or impaired function, it can be cheaper to repair impaired components than to replace them. In some cases, an improvement in the function of a part can involve cleaning. Automotive parts washers provide a venue for the safe and effective cleaning of dirty automotive components.
Some industrial parts washer manufacturers fabricate washers designed specifically to handle automotive parts washing, making the cleansing of small engines, transmissions, pneumatic parts, hydraulic parts and small parts much easier and more effective.
Many automotive parts can be washed by standard parts washers, but some parts cleaners are tailored specifically to serve the automotive industry. Aqueous hot water solutions are generally used in automotive parts washers as well as ultrasonic cleaning tubs for fast precision cleaning.
Automotive parts washers for auto repair shops are generally cabinet or tub spray washers, which use organic biodegradable solvents. Part washers for transmissions, engines, and farm equipment parts, in particular, are usually more specialized. Ultrasonic washers are used on complex parts that require a high level of surface purity and function by using high-frequency vibrations to create cavitations that help to clean even the very small holes and internal crevices of a part that other cleaning methods cannot reach. Automotive industrial washers often use ultrasonic cleaning to reduce the risk of malfunction due to part contamination.
The automotive industry concerns itself with the precision with which all of the constituent parts of an automobile are manufactured; the failure of even one part can be catastrophic in terms of engine performance, and in extreme cases, in terms of driver safety. Therefore, it is incredibly important to have an automotive parts washer that can thoroughly clean components and ensure the optimal performance of the assembled vehicle.
