• After each use: Clean the inside of the autoclave and around valve and vents o Empty all water from chamber and thoroughly dry o Wipe off metal-to-metal seal with clean towel to remove build-up • Make sure valves are not clogged o Periodically clean control valve with hot, soapy water • Check air exhaust tube by flushing water through it to make sure it is not blocked. • Descale the chamber: most effective to use detergent meant for lime scale removal. Vinegar diluted with distilled water can also be used. • Check for signs of wear and damage. Ensure sufficient seal around lid: o For a metal-to-metal seal, lubrication of the seal must be maintained o For a gasket seal, the seal must be pliable. If it is cracked or dry, then it should be replaced • Valve safety check: Test the safety pop-off any time there is pressure built up in the sterilizer. Test the valve below the operating pressure with the use of a screwdriver to pop the pressure relief valve. Make sure your hand is away; otherwise the steam can cause burns.
