Quality Precision Cleaning, Inc. (QPC) provides precision cleaning, passivation, and testing for aerospace, military, medical, and commercial manufacturers, operating a certified Class 7 clean room in Irwindale, California, plus a second facility in Washougal, Washington. QPC is not a residential or janitorial cleaning company — every part that comes through the door is measured, certified, and traceable.
Every service runs under the same AS9100D / ISO 9001:2015 quality system, from raw part to certified report.
Contaminant removal inside our Class 7 clean room, with Class 5 laminar flow workbenches, for parts and assemblies from the minutest details up to 11'W × 50'L × 11'H.
Removal of free iron from stainless steel surfaces to restore corrosion resistance after forming and cutting. Citric Acid Passivation is our preferred, lower-impact method.
Verification that fabricated and assembled parts meet spec before they ship — validating the design and manufacturing process, not just the cleaning step.
