Autoclave Maintenance in Vancouver

Chamber Interior & Internal Surfaces How to Properly Maintain the Sterilization Chamber

The sterilization chamber is the core of the autoclave system and plays a direct role in heat transfer, steam circulation, and overall sterilization performance. Over time, residue from minerals, detergents, and improperly rinsed instruments gradually builds up on the chamber walls, tray rails, and internal surfaces.
In Vancouver, mineral residue forms faster due to local water quality and frequent daily cycles. Without consistent Autoclave maintenance, this buildup acts as an insulating layer, interfering with proper heat transfer and disrupting uniform steam circulation inside the chamber.

Step by Step Guide

Proper chamber cleaning should be performed methodically to avoid damaging the stainless steel surface.
Power Down and Cool the Unit
Turn off the autoclave, unplug it , and allow the chamber to cool completely. Never clean the chamber while it is hot or pressurized.
Remove Trays and Racks
Take out all trays, racks, and accessories. These should be cleaned separately using mild detergent and thoroughly rinsed to prevent detergent residue from re entering the chamber.
Inspect the Chamber Surface
Visually inspect the chamber walls, floor, and tray rails for mineral buildup, staining, or residue. Pay close attention to corners and weld seams where deposits tend to accumulate first.
Apply an Approved Chamber Cleaner
Use a manufacturer approved autoclave chamber cleaner or a recommended non abrasive solution. Apply it evenly using a soft, lint free cloth or sponge. Never use steel wool, abrasive pads, or harsh chemicals, as these can damage the stainless steel and accelerate corrosion.
Gently Clean All Internal Surfaces
Wipe the chamber walls, floor, and tray rails using light pressure. The goal is to remove residue, not to scrub aggressively. Persistent buildup may require repeating the process rather than increasing force.
Rinse Thoroughly
After cleaning, wipe the chamber multiple times with clean distilled water to remove any remaining cleaning solution. Residual chemicals left inside the chamber can affect future sterilization cycles and indicator results.
Dry the Chamber Completely
Use a clean, dry cloth to remove excess moisture . Leaving moisture behind contributes to mineral spotting and shortens the time between required Autoclave maintenance visits.
