Specialty Cleaning

Macfab offers specialty cleaning in an ISO-compliant cleanroom meeting level 7 requirements. Our customers achieve financial savings when components shipped to them require no additional cleaning or finishing on their part. Our internal capability provides end-to-end solutions for your precision components and sub-assemblies, cutting supply chain risks and transportation costs to reduce the paid cost for the part – ultimately lowering your total cost of ownership.

With the growing trend of customers having their non-core services outsourced to trusted partners, Macfab responded by making significant investments in the specialized finishing and cleaning capabilities that are a direct, logical and cost-effective extension of our machining and manufacturing operations.

The following table is a quick overview of cleaning methods and their benefits.

Cleaning MethodApplicationBenefits
Aqueous (Water) cleaning solutionsPart cleaning and removal of films



Non-aqueous (Non-water) cleaning solutionsBreaks down the bonds of oils, greases, and cutting fluids on the parts

More thorough cleaning reduces the risk of oxidation

Magnetic deburringRemoves light burrs from non-ferrous small parts and improves surface finish


No coating or fluids required

Vapor degreasingDissolve contaminates and collects in a tank below, preparation of parts for painting or coatings


Can be used on a wide range of parts

Micro electro-polishingRemoval of microscopic burrs improves surface finish and connection between parts

Extreme precision and control of the process

Citric acid passivation to ASATM-A967-13Used on stainless steel to prevent corrosion

Removes free iron ions and forms a protective barrier over the part.


CNC Milling for Custom & Mass Manufacturing Solutions

Macfab follows the ISO Standard 16232 of cleanliness for components and systems and confidently achieves a contamination level below 6 by utilizing these tight controls:

  • Water purification using R.O., ultra-filtration, de-ionization, and UV sterilization
  • High-purity aqueous & non-aqueous cleaning solutions (HPLC grade)
  • Purifying and recycling all waste solvents

Cleaning parts in-house aligns strategically with Macfab’s on-site coating processes. The immediate cost elimination of transportation makes a significant impact on the cost of ownership. Reducing the time between cleaning and coating reduces the chance of corrosion or handling damage. By running exceptionally clean parts through our own coating process, Macfab has a reliable system and greater production capacity.

Macfab’s engineering team looks forward to reviewing your part’s cleanliness requirements and suggesting the optimal process to achieve a clean, cost-effective part.
