Stains on your a medical instrument can be removed, but rust can leave damage forever. So how do you know if a brownish-orange color is rust or a stain, use the eraser test. Use the eraser and it back and forth until the discoloration has been removed and the surface underneath is smooth and clean, then that means it’s a stain. However, if a pit mark shows up on the metal after the discoloration has been removed, then this is corrosion, which will continually rust.

Troubleshooting Stain Guide:

Orange/Brown Stains – Most individuals think that when they notice orange/brown stains that it is rust. When this stain color appears as a result of PH surface deposits, it is a result of any of the following: Chlorhexidine usage, improper soaps and detergents, cold sterilization solution, possibly baked-on blood, soaking in saline or using laundry soap.
Black-ish Brown Stains – Low PH (less than 6) acid stain. It may be caused by dried blood and/or improper soaps and detergents.
Blackish-Blue Stains – Reverse planting may happen when different metals are ultrasonically processed together. For example, when you have stainless steel surgical instrument sets precede with chrome surgical instruments will cause a stain color reaction. This blueish black stain will occur if blood, saline or potassium chloride will make this bluish black stain appear.
All-in-one color stains – Excessive heat by a localized “hot spot” in the processing cycle.
Dark and Light Spots – When you allow
to air-dry. With slow evaporation, the minerals (sodium, calcium and magnesium) are left on the medical instrument’s surface.
Bluish Gray Stains – This happens whenever cold sterilization is being used outside a manufactuer guidelines.
Black Stains – Whenever amonia is present.
