This guide will walk you through everything you need to know about immersion parts washers.
What is an Immersion Parts Washer?
An immersion parts washer is a washing system that submerges parts fully in an agitated cleaning solution, contained in a wash tank.
This method is ideal for washing parts with complex shapes, small holes, or internal channels. Because the part is fully covered by the cleaning solution, every surface has contact with the detergent. This leads to a deeper and more even clean.
How Does an Immersion Parts Washer Work?
The process is straightforward but very effective. Parts are placed into a basket or directly into the tank. The tank contains heated water mixed with a cleaning detergent. Once the cycle starts, several actions take place at the same time.
- Heat softens oils and grease. Warm water allows the detergent to work faster and more effectively.
- Chemistry then plays its part. Specially formulated detergents break down contaminants so they can be lifted from the surface.
- Movement helps loosen dirt. This can be done through agitation, circulation pumps, or even ultrasonic waves. Ultrasonic cleaning uses high-frequency sound waves that create tiny bubbles. These bubbles collapse and release energy, which helps remove grime from tight spaces.
- The final factor is time. Leaving the parts submerged for the right amount of time allows the solution to reach every area.
What About Drying?
After washing, drying is the next step. Wet parts can develop rust or water marks if left untreated. Many immersion systems include built-in drying options, such as heated air blowers or drying chambers.
What Can You Clean with an Immersion Washer?
Immersion washers can handle a wide range of components. They are especially useful when parts have deep recesses, threads, or narrow channels.
Common applications include:
Automotive Parts
Engine parts, fuel injectors, gear components, and bearings.
Aerospace Components
Turbine blades, valves and hydraulic parts.
Medical Instruments
Surgical tools, implants, and dental equipment.
Manufacturing Parts
Machined parts, mould tools and fabricated components.
Types of Immersion Parts Washers
Not all immersion washers are the same. Different models suit different tasks and production levels.
Manual Immersion Tanks: Simple and cost effective. Operators place and remove parts by hand. These systems are often used in smaller workshops or maintenance areas.
Agitated Immersion Washers: Pumps or mechanical movement is used to stir the cleaning solution. This added motion improves cleaning power without increasing chemical strength.
Ultrasonic Immersion Washers: High-frequency sound waves are added to the cleaning process. They are ideal for precision parts, delicate components, and detailed surfaces.
Multi-Stage Immersion Systems: These include several tanks for washing, rinsing, and drying. These are suited to higher production volumes where consistent results are vital.
Each type offers its own balance of speed, cleaning depth, and cost. So how do you pick the right one for your business?
Choosing the Right Immersion Parts Washer
Selecting the right industrial parts washer starts with understanding your cleaning needs. Think about the size, material, and level of contamination of your parts. Remember, parts with fine details or internal passages benefit most from immersion cleaning.
You’ll need to consider:
- The size of your parts
- How dirty your parts get
- How many parts need cleaning each day
- Detergent choice
- Cycle time and temperature
- Rinsing and drying needs

Key Benefits
Deep, Thorough Cleaning
Parts are fully submerged, so the cleaning solution reaches every surface, including holes, threads, and hidden channels.
Improved Cleaning Consistency
Automated immersion systems provide repeatable and consistent cleaning results.
Flexible Cleaning Options
Choose from basket rotation, spray under immersion, or ultrasonic cleaning options.
Reduced Labour
Once the cycle starts, the machine does the work. Operators spend less time handling parts and scrubbing surfaces.
Gentle on Parts
There is no harsh brushing. This lowers the risk of scratches or wear, even on delicate components.
