WHAT IS STAINING?
Staining is a surface deposit on instruments that is most often mistaken for rust. After autoclaving, you may notice a stain on your instruments. Rusting instruments are very rare. Stains on instruments appear in many colors and, in most cases, the colors tell you about the origin of the stain.
ADDITIONAL STAINING INFORMATION
As described, stains are either deposited onto an instrument's surface, plated on or, in the case of rusting, developed from the instrument itself. The most common discoloration is due to deposit stains and usually occur during autoclaving.
To minimize staining, it is important that the autoclave runs perfectly, and that it has a well-functioning drying cycle. The instruments should come out completely dry, whether in wrappers or loose on a tray. If any moisture is left in the pack or on the instruments, it will result in tiny water droplets on the instrument surface, which will leave a circular stain after drying. The color of this stain will depend on the pH as well as the mineral or metal contents of the water. If the drying cycle works perfectly, however, there is much less chance for deposits to form on the surface of the instrument.
Stains due to metal deposits or plating stains are always near the most magnetic parts of the instrument. New instruments are often highly magnetic in the locks, the serrations, and ratchets. This happens because the carbon steel tools used to work on the instruments during production are very magnetic themselves. This magnetism wears off gradually during handling and sterilization. This is the reason why newer instruments tend to stain more visibly.
