Strata-G and Fusion rings should be cleaned before sterilization with a soft plastic brush and warm water. You can use a mild detergent alongside warm water if needed (no harsh chemicals should be used in this process). Sterilization is not a substitute for proper cleaning. If debris has accumulated due to improper cleaning, the use of a scaler or other metal instrument may be needed to gently scrape the debris from the ring tips. Debris does not negatively impact ring performance or reduce ring life; it's simply not aesthetically pleasing. To sterilize the rings, steam autoclave only.
