Hot Oil
Method:
Some dentists and physicians use hot oil at 160oC for the sterilization of instruments. A time period of 1 hour is usually recommended.
Advantages:
Hot oil does not rust metals, and minimal corrosion takes place. However, once sterilization is complete, the instruments must be cleaned and dried for storage, and this steam may reintroduce contamination.
Another Method:
Silicone is sometimes used as an alternative to oil.
