Proper Cleaning of Surgical Instruments to Avoid Rust & Stains
Understanding the difference between Rust vs. Stains on surgical instruments.
Stains can be removed, whereas rust will leave permanent damage. To determine if
a brown/orange discoloration is a stain or rust, use the eraser test. Rub a pencil
eraser aggressively over the discoloration. If the discoloration is removed with the
eraser and the metal underneath is smooth and clean, this is a stain.
If a pit mark appears under the discoloration, this is corrosion or rust.
