Ultrasonic Cleaning & Disinfection •  Place the knife (with blade in the fully retracted position) in an ultrasonic unit filled with warm distilled/deionized water (65.5°C/150°F) along with a neutral pH cleaner for 2 to 3 minutes. The knife may be fully immersed with the 		 blade fully retracted in a small ophthalmic 		 dedicated ultrasonic cleaning unit.
