
Cassettes should be placed on the tray rack in place of the trays. They should not
be touching each other or the Chamber walls. There should be about 2.5cm
between cassettes or packs for proper steam circulation.

If spotting is detected on the instruments it is necessary to determine if the spot is
dirt or rust. The first step would be to use an ordinary eraser to remove the spot. If
there is no pitting under the spot, then the spot is only dirt. Dirt spots on an
instrument may be an indication that the autoclave needs to be cleaned or that the
instruments were not adequately cleaned or dried prior to sterilization. If removal of
the spot reveals pitting, then the spot is most likely rust. Rust spots on an
instrument are not uncommon on inexpensive instruments. It may also be an
indication that the instruments were rinsed in tap water with a high mineral content.
These minerals when exposed to high temperature and steam will accelerate the
oxidation of the metal. One suggestion would be to final rinse the instruments in a
distilled water bath and pat dry to absorb residual water and minerals.

If the instruments exhibit a discoloration this can be due to the mixing of carbon
steel and stainless steel. When these two metals come into contact with each other
electrolysis occurs that breaks down the metal. The best solution is to separately
wrap the carbon steel instrument to insulate it from other instruments on the tray
and the tray itself.
