What’s a parts washer?

Parts washers clean industrial components coated in grease and oil, extending their lifespan and maximizing performance. They use solvent or water-based media and different operating mechanisms, from soak units to direct spray cleaning machines. Maintenance is required to replace dirty water or solvents, and filters can be used to capture contaminants.

A parts washer is a device used to clean manufacturing and industrial components. During normal operation, these parts can become coated in grease and oil, which can prevent the parts from working as intended. A parts washer removes grease and other contaminants from these parts, which can help extend the life of the part while maximizing performance. Washer models can range from simple drums or barrels to fully automated room-sized cabinets. Industrial units can be found in factories or industrial plants, while smaller portable models are used in small repair shops or home garages.

These machines rely on a variety of media to clean the engines and other parts. Some are solvent based and use petrochemicals to clean parts quickly and effectively. While solvent-based parts washers tend to offer the most effective cleaning, they also pose a threat to the environment in terms of disposal and maintenance. Aqueous or water-based washers offer an economical and environmentally friendly solution to solvent-based systems, but may not be able to remove all types of soiling. Some factories have turned to washers for bioremediation parts, which use bacteria to eliminate harmful compounds in solvents before disposal.

Parts washer units use different types of operating mechanisms to clean parts. Soak units are the simplest and consist of a large barrel filled with water or solvent in which the parts are left to soak until clean. These models tend to be the least effective at removing serious grease and grime. Brush units include a series of brushes to aid in the grease removal process and in some cases may combine soaking and brushing.

For more effective cleaning, direct spray cleaning machines spray water and solvent onto a part in a steady stream. Pressure spray units offer an even more effective version of this technology. The most laborious parts washers are those with a built-in pump. These pumps agitate the parts and fluid inside the washer, similar to how a washing machine works. Some may even incorporate ultrasonic waves to clean parts even more effectively.

All parts washer units require some degree of maintenance to remove dirty water or solvents and replace them with fresh cleaning solutions. A filter inside the washer tank can reduce the frequency of this maintenance and help the solvent or water last longer and clean better. Advanced units feature built-in filters to capture oil and other contaminants. A simple automotive filer can be placed in units without built-in filter systems to perform a similar function.
