How to Clean an Autoclave: Step-by-Step Guide

Autoclave maintenance through proper cleaning methods preserves the effectiveness and safety of sterilization procedures in both medical and laboratory operations. Medical device distributors, dealers and procurement professionals must ensure proper cleaning and maintenance of autoclaves to achieve compliance and equipment durability while preventing contamination. Failure to clean autoclaves regularly leads to equipment breakdowns, expensive maintenance needs and increased danger to patient safety. This guide delivers thorough autoclave cleaning instructions designed specifically for professionals who manage sterilization equipment supplies and maintenance.

Safety Precautions Before Cleaning

The safety of personnel must be the top priority before starting any cleaning procedure on your autoclave. Here are the key precautions to follow:

1. Power Down the Autoclave

  • Before you start cleaning the autoclave you must turn it off and wait until it reaches a safe temperature.

  • The unit should be unplugged from the electrical outlet to protect against unintended activation.

2. Wear Appropriate Personal Protective Equipment (PPE)

  • Protect yourself from burns and chemical exposure by wearing heat-resistant gloves along with safety goggles and a lab coat or apron to avoid contamination.

3. Ventilate the Area

  • Maintain proper ventilation in the cleaning area to prevent inhaling hazardous fumes from cleaning chemicals.

4. Read the Manufacturer’s Manual

  • The autoclave’s user manual provides essential cleaning procedures and safety instructions which should be consulted regularly.


Step-by-Step Cleaning Process

1. Remove Trays and Racks

  • Gently remove each tray, rack and all other detachable parts from the autoclave.

  • Place these components into warm soapy water to help remove debris and contaminants.

2. Clean the Chamber

  • Use a gentle, non-abrasive cloth or sponge to clean the interior surfaces of the chamber.

  • Use cleaning products that are both gentle and non-corrosive which have received autoclave use approval.

  • Corners and crevices require thorough cleaning because residue tends to build up in these areas.

3. Descale the Chamber (If Required)

  • Mineral deposits known as scale tend to accumulate inside the chamber when your facility uses hard water.

  • To eliminate mineral deposits inside autoclave chambers use a descaling solution which is specifically formulated for autoclaves.

  • Make sure to rinse completely using distilled water to eliminate any chemical residues.

4. Clean the Door Gasket

  • Examine the door gasket closely to find any debris, cracks, or indications of wear.

  • Use a moist cloth with mild detergent to gently wipe the gasket clean.

  • Do not use sharp tools or rough materials to clean the gasket as they can cause damage.

5. Clean the Drain Lines and Water Reservoir

  • Perform routine flushes of the drain lines to avoid blockages.

  • Use distilled water to rinse the empty water reservoir until it’s free from detergent and contaminants.

6. Reassemble and Inspect

  • Once every component has dried completely the autoclave should be reassembled.

  • Examine the system for any detached parts or indications of damage.

7. Test Run the Autoclave

  • Conduct an empty cycle to verify proper operation and remove any leftover cleaning solutions.


Recommended Cleaning Agents

An appropriate cleaning agent selection ensures efficient maintenance of autoclave systems.

  • Choose pH-neutral detergents specifically designed for stainless steel surfaces as mild and non-corrosive cleaning agents.

  • Autoclave chamber cleaning requires solutions specifically designed for removing mineral deposits.

  • Ensure the use of distilled water for rinsing to prevent mineral deposits from forming.

Important: Avoid using bleach and abrasive powders as well as harsh acids because they can cause damage to both the chamber and components.


How Often Should You Clean Your Autoclave?

The cleaning schedule for your autoclave should match both how often it is used and the nature of the loads processed. Here is a general guideline:

  • Each time you use the autoclave clean the chamber surface together with trays and the door gasket.

  • Perform a thorough cleaning of the chamber, trays, racks and drain lines every week.

  • Every month you should perform descaling on the chamber while inspecting it for wear or malfunction indicators.
