Part cleaning is a critical step in manufacturing. During production, metal components are typically coated with oils, greases, coolants, and lubricants after machining or forming. If these residues are not removed properly, they can interfere with coatings, reduce paint adhesion, and accelerate corrosion. Furthermore, effective part washing ensures performance, quality, and long-term reliability. At the same time, manufacturers must balance wash performance with cost control. While part cleaning adds expense to production, it is minor compared to the cost of rejected shipments, rework, or reproducing damaged parts. For this reason, manufacturers rely on structured cleaning strategies to protect both quality and profitability.
That is why manufacturers use different part washing methods depending on the type of metal, soil level, and production environment. In other words, no single cleaning method fits every application.
Common processes include:
Immersion
Spray
Wet vapor blasting
Vapor honing
Ultrasonic
Hand
Vibrating tumblers
ZERUST® enhances each of these processes by:
Reducing total cleaning time
Improving surface preparation and adhesion
Preventing flash corrosion after washing metal parts
Lowering rework and rejection rates
Below is a breakdown of how ZERUST® solutions improve each method.
Improve Your Part Cleaning Performance
Discover high-performance parts washer fluids engineered to enhance washing metal parts, reduce flash corrosion, and improve washing efficiency across your operation.
Immersion cleaning is widely used for heavy degreasing and descaling. In this process, parts are submerged in a cleaning solution designed to remove:
Straight oils and soluble oils
Metalworking fluids
Forming lubricants
Carbon scale
Heavy soils and greases
Tramp oils
For immersion part cleaning, ZERUST® offers a range of industrial cleaners that remove hydrocarbon soils while minimizing corrosion risk. In addition, these cleaners are engineered to maintain surface integrity after washing. Recommended products include:
AxxaWash™ KF-121 – Low-foaming alkaline metal cleaner for light-to-medium hydrocarbon soils, ideal for immersion systems.
AxxaWash™ KF-122– Heavy-duty, hard-water compatible alkaline cleaner suitable for immersion part cleaning.
AxxaWash™ KF-123 – Mildly alkaline cleaner that inhibits flash rust in immersion washes.
AxxaWash™ KF-124– Mildly alkaline, flash-rust inhibiting cleaner for immersion applications.
AxxaWash™ KMS-220– Low-foam part cleaner with excellent oil-splitting capabilities, compatible with immersion tanks.
AxxaWash™ KMS-310AL – Aluminum and ferrous cleaner that can be used in immersion to remove medium-duty soils.
AxxaWash™ NW-10C – Alkaline preservation cleaner that deactivates chlorides and oils and is effective in immersion.
AxxaWash™ NW-12C – Extended flash-rust inhibiting cleaner usable in immersion systems
These solutions improve part cleaning results while helping protect components during staging, storage, or transfer. As a result, manufacturers reduce downstream corrosion issues and improve overall reliability.
Spray Cleaning Systems
Spray cleaning uses a pressurized solution to remove contaminants from metal surfaces. Because of its speed and consistency, it is common in automated production lines where consistent washing of metal parts is essential.
For spray cleaning and washers where you are washing metal parts under low to medium spray pressures, include:
AxxaWash™ KF-121 – Effective under spray conditions and removes light-medium soils.
AxxaWash™ KF-122 – Heavy-duty spray suitable for hard water systems.
AxxaWash™ KF-123– Flash-rust inhibiting, appropriate for spray part washing.
AxxaWash™ KF-124– Flash-rust inhibiting spray that performs well at lower temperatures.
AxxaWash™ KMS-305AL– Aluminum compatible solution formulated specifically for spray use with oil-splitting performance.
AxxaWash™ KMS-310AL – Versatile cleaner that also performs well in spray systems.
AxxaWash™ NW-10C– Can be used as a spray solution that deactivates soils and corrosion sources.
AxxaWash™ NW-12C – Extended flash-rust protection usable in spray modes.
By integrating corrosion inhibition into the part cleaning stage, manufacturers reduce downstream failures. Consequently, surfaces remain stable between cleaning and packaging.
Wet Vapor Blasting
Wet vapor blasting combines pressurized water with abrasive media to remove coatings, corrosion, and embedded contaminants. As a result, this process is effective for restoring surfaces and preparing components for refinishing.
After aggressive cleaning, flash corrosion can occur quickly. ZERUST® addresses this risk with:
AxxaVis™ WBA-10 – Counters corrosive anions on metal surfaces and provides extended flash corrosion inhibition. Hard water capable.
For operations that rely on washing metal parts with abrasive systems, adding corrosion control improves consistency and surface stability. Therefore, components remain protected even in demanding environments.
Vapor Honing for Precision Parts
Vapor honing is similar to wet vapor blasting but is typically performed in smaller cabinet systems. Because of its controlled environment, it is ideal for smaller machined components and precision parts.
Benefits of vapor honing include:
Dust-free process
Simultaneous degreasing and blasting
Longer media life
Softer surface finish
Reduced media embedding
To enhance part cleaning performance, ZERUST® offers:
AxxaVis™ WBA-10 – Treats chlorides and water hardness while preventing flash corrosion after washing metal parts.
This ensures surfaces remain clean and protected after processing. Ultimately, it helps maintain dimensional integrity and finish quality.
Ultrasonic Cleaning
Ultrasonic cleaning uses cavitation created by high-frequency sound waves to loosen and remove soils. As a result, it is highly effective for intricate components and tight geometries.
Ultrasonic part cleaning systems benefit from cleaners formulated to degrease and remove soils without cavitation damage. For this reason, selecting the proper chemistry is critical. Add the following:
AxxaWash™ KF-121– Works in ultrasonic systems for light-medium soils.
AxxaWash™ KF-122– Suitable for ultrasonic systems in harder water conditions.
AxxaWash™ KF-123– Mild alkaline with flash-rust inhibition for ultrasonic washes.
AxxaWash™ KF-124– Flash-rust inhibiting that is compatible with ultrasonic baths.
AxxaWash™ KMS-310AL– Multi-mode product effective in ultrasonic systems for aluminum and ferrous parts.
AxxaWash™ NW-10C– High-performance product that deactivates corrosion sources in ultrasonic cleaning.
AxxaWash™ NW-12C – Designed for ultrasonic usage with extended flash-rust inhibition.
These products allow manufacturers to improve cleaning efficiency while minimizing corrosion risk after washing metal parts. In turn, this supports higher production throughput.
Hand Cleaning Applications
Hand cleaning is often used for specialty parts, rework areas, or low-volume production. However, it can be inconsistent and labor-intensive.
When washing metal parts manually, corrosion control is especially important. Without proper inhibition, residual moisture and inconsistent drying can lead to rapid oxidation.
ZERUST® solutions for manual part washing include:
These solutions simplify hand cleaning while improving consistency and corrosion resistance. As a result, operators achieve more predictable outcomes.
Vibrating Tumblers
Vibratory tumbling systems clean, deburr, polish, and descale smaller components using controlled vibration and media movement.
This method is ideal for high-volume part washing of small components. Additionally, it supports consistent surface finishing across batches. To enhance washing metal parts in vibratory systems, ZERUST® offers:
Adding corrosion inhibition to vibratory part cleaning reduces the risk of oxidation between washing and packaging. Therefore, manufacturers maintain surface quality through the next production stage.
