From jet fighter landing gear to rifle barrels, Graymills helps match the right cleaning system to the mission
Graymills provides parts washer systems for military maintenance operations, government buyers, and weapons and munitions manufacturers that need effective cleaning of components ranging from large mechanical assemblies to smaller precision parts. From landing gear and mechanical systems to rifle barrels and other hard-to-clean components, Graymills offers cleaning solutions designed for demanding military applications.
In these environments, parts cleaning must be effective, environmentally responsible, and adaptable to both maintenance and production workflows. Graymills helps make that No Confusion by offering manual, immersion, ultrasonic, and spray cleaning systems, along with solvent and aqueous cleaning chemistries to match the part, soil, and process.
It also means No Risk. Graymills can evaluate different cleaning methods and chemistries on your sample parts in its test lab and provide documented results to help identify the best solution before purchase.
And it means No Worries. Graymills parts washers are manufactured in the USA, backed by long experience supporting military and government applications, and available with customization options such as automated loading and unloading, temperature controls, and multi-stage clean, rinse, and dry processes.
Graymills also offers products with multiple NSNs, equipment compatible with MIL-PRF-680 applications, and GSA purchasing support to help simplify procurement.
Whether the requirement is for depot maintenance, base-level service, or weapons and munitions manufacturing, Graymills can help you find the right parts cleaning solution.

What types of military and firearm-manufacturing components require industrial parts washing?
Military parts washers are used to clean a wide range of components, including engines, transmissions, hydraulic components, structural assemblies, ground-support equipment, weapons-related parts, firearm components, and munitions-related parts. In firearm and defense manufacturing, this can include barrels, trigger mechanisms, housings, machined components, and other precision parts that need to be cleaned before inspection, assembly, coating, or finishing. Graymills systems are used to remove grease, oil, carbon buildup, machining chips, preservative coatings, and handling residue from both precision parts and heavier assemblies.
Does Graymills offer parts washers with NSNs?
Yes. Graymills states that it maintains dozens of National Stock Numbers, which can help military and government buyers streamline procurement through established supply channels.
Are Graymills parts washers compatible with MIL-PRF-680 solvents?
Yes. Graymills states that its parts washers work effectively with MIL-PRF-680 solvents commonly used in military degreasing applications. That makes Graymills relevant for installations and manufacturers that need equipment compatible with established military cleaning practices.
Is Graymills available through GSA?
Yes. Graymills states that it is available through GSA Contract GS07F5729P, which can help speed ordering and delivery for eligible government buyers.
What cleaning methods are used in military installations and firearm manufacturing?
Graymills offers multiple cleaning methods for military and firearm-related applications, including:
- manual solvent cleaning
- aqueous spray wash systems
- immersion cleaning
- ultrasonic cleaning
- multi-stage wash, rinse, and dry systems.
The right method depends on the size of the component, the type of contaminant, the complexity of the geometry, and the required cleanliness result.
Can military parts washers be customized?
Yes. Graymills can customize systems to fit specific military, depot, or firearm-manufacturing requirements. Graymills specifically notes customizations such as:
- automated loading and unloading
- temperature controls
- filtration
- auto water fill
- multi-stage clean, rinse, and dry configurations.
That makes the line a better fit for installations and manufacturers that need more than a standard off-the-shelf washer.
What contaminants are typically removed in military and firearm parts cleaning?
Common contaminants include grease, lubricants, carbon deposits, hydraulic fluid, machining chips, metal fines, preservative coatings, assembly residue, and handling residue. In firearm and weapons-component manufacturing, cleaning may also be needed to remove oils, debris, and process residues from machined parts before coating, assembly, or inspection. The right cleaning process depends on the part, the residue, and the next manufacturing or maintenance step.
How are parts washers used in firearm, weapons, and munitions manufacturing?
In firearm, weapons, and munitions manufacturing, parts washers are used to remove machining oils, chips, debris, and other residues from components before inspection, assembly, coating, or finishing. That can include both larger assemblies and smaller precision parts with more detailed geometries. Consistent cleaning helps improve repeatability and supports the next production step by reducing contamination-related variability. Graymills’ military page explicitly addresses weaponry and munitions manufacturing as part of this market.
Are Graymills systems suitable for cleaning smaller precision firearm components?
Yes. Graymills specifically highlights benchtop ultrasonic cleaners for parts with holes and hard-to-reach surfaces, which makes ultrasonic cleaning especially relevant for smaller precision components with tighter internal features or more intricate geometry. For firearm-manufacturing environments, that can make ultrasonic cleaning a strong option when detailed, repeatable cleaning is required for smaller machined parts.
Can Graymills support military installations worldwide?
Yes. Graymills states that it has successful installations from Okinawa to Germany and describes a long history of working with military customers and government buyers.
How do multi-stage wash systems improve military maintenance and defense manufacturing operations?
Multi-stage wash systems improve military maintenance and defense manufacturing operations by separating cleaning, rinsing, and drying into more controlled steps. This can improve contamination control, reduce cross-contamination, and support more repeatable maintenance, rebuild, and production outcomes. Graymills specifically recommends multi-stage clean, rinse, and dry as a customization option for this market.
Are aqueous systems available for military applications?
Yes. Graymills offers both manual solvent and automated aqueous cleaning systems for military applications. Aqueous systems are often selected when buyers want a more process-controlled cleaning method or reduced solvent handling, depending on the application and operating requirements.
Can Graymills test military or firearm-manufacturing parts before equipment selection?
Yes. Graymills states that its test lab can evaluate sample parts using different cleaning methods and chemistries and provide documented video results. This is one of the strongest trust-building points on the page because it reduces guesswork before equipment procurement or process selection.
Are Graymills parts washers manufactured in the USA?
Yes. Many Graymills parts washers are manufactured in the USA.
Can Graymills support cellular manufacturing environments in defense and weapons production?
Yes. Graymills can support cellular manufacturing environments in defense and weapons production with cleaning systems that fit close to the work area and help keep parts moving between operations. This is especially valuable when components need to be cleaned between machining, inspection, coating, assembly, or finishing without creating extra handling or workflow delays. Depending on the application, Graymills can provide compact immersion, ultrasonic, spray, or modular wash/rinse/dry systems that support repeatable cleaning within or alongside a production cell. This helps manufacturers improve consistency, reduce bottlenecks, and match the cleaning process to the part, contaminant, and production step.
How do industrial parts washers support military readiness and production reliability?
Industrial parts washers support military readiness and production reliability by helping teams clean components thoroughly before inspection, repair, rebuild, coating, assembly, and return to service. Better cleaning can improve inspection accuracy, reduce contamination-related issues, and help maintenance and manufacturing operations move more consistently.
