Mineral buildup can be costly to repair and causes downtime so detecting it early is essential. These common indicators show that your autoclave has mineral deposits.
The interior surfaces of chambers and trays and water reservoirs develop a persistent white or gray chalky coating which standard cleaning methods fail to eliminate.
Extended heating and pressurizing times during autoclave cycles show that scale buildup is creating an insulating barrier around heating elements.
When an autoclave displays error notifications about temperature levels, pressure values or water volume measurements it could be experiencing blockages or sensor disruptions caused by scaling buildup.
Musty or metallic odors in the chamber or reservoir develop when water becomes stagnant and minerals accumulate.
The presence of mineral deposits on sterilized instruments indicates compromised water quality or internal scaling when mineral-laden steam produces spots.
The need for more regular repairs and cleaning cycles indicates a buildup of minerals inside the system.
Descaling involves the regular removal of mineral deposits particularly necessary in regions with hard water conditions. This section provides a step-by-step process to safely remove scale from your autoclave:
Autoclave-specific descaling solution (pH-neutral and non-corrosive)
Distilled water
Soft, non-abrasive cloths or sponges
Personal protective equipment (gloves, eye protection)
Measuring cup or container
Before you begin make sure the autoclave is turned off and has completely cooled down.
Extract all detachable components from the autoclave and place them in a separate location for individual cleaning.
Follow the manufacturer’s guidelines to empty the water reservoir.
Safely discard old water because it contains concentrated minerals.
Prepare the descaling solution by following dilution instructions provided on the product label or manufacturer’s guidelines.
Transfer the solution into the reservoir until it fully encompasses all impacted surfaces.
The solution needs to remain in place between the manufacturer suggested time of 30–60 minutes to break down mineral deposits.
To remove deposits from the chamber and trays and other reachable parts use a gentle scrubbing motion with a soft cloth or sponge.
Do not use harsh brushes or pads which can damage stainless steel surfaces.
Remove all the descaling solution from both the reservoir and the chamber.
Run a full sterilization cycle without any instruments but with distilled water in the reservoir to remove remaining residues.
Perform the rinsing procedure at least two times to remove all traces of the descaling agent.
Inspect every surface to see if any deposits or residues remain.
Reinstall trays, racks, and accessories.
Use a damp cloth that lacks lint to clean all external surfaces.
Maintain regulatory compliance by logging the date of descaling, products used during the process, and any additional observations for future reference.
Prevention is always more efficient than remediation. These tested methods will help reduce mineral buildup in the future.
Tap water contains minerals that cause scaling. Sterilization and rinsing procedures require distilled water because it contains no impurities.
Perform daily or weekly cleaning of the chamber, reservoir, and components as required.
Descaling should occur according to the manufacturer’s schedule or at increased frequency when operating in hard water regions.
Continually check water hardness levels when your facility experiences changes in water supply.
Set up water treatment systems like softeners or filters when needed.
Instruct employees to identify the initial signs of scale buildup so they can take swift corrective action.
Use only descalers and detergents that are compatible with medical autoclaves. For more information, see: .
Schedule regular inspections by qualified technicians to ensure all components are free of buildup and functioning correctly.
Mineral deposits are a common but preventable challenge for anyone responsible for autoclave maintenance in the medical device industry. By understanding why mineral buildup occurs, recognizing the warning signs, and following a systematic descaling process, you can safeguard your equipment, ensure optimal sterilization, and reduce costly downtime. Preventive practices, such as using distilled water and regular descaling, are essential for maintaining compliance and protecting your investment. Empower your team with the knowledge and tools to keep your autoclave running efficiently and reliably.
A: The frequency depends on water quality and usage. In areas with hard water, monthly descaling is recommended. Otherwise, follow the manufacturer’s guidelines or descale at least quarterly.
A: No. Household descalers and vinegar may be too harsh and can damage autoclave components. Always use products designed for medical autoclaves.
A: Ignoring scale buildup can lead to inefficient sterilization, equipment malfunction, longer cycle times, and even costly repairs or replacements.
A: Routine descaling can typically be performed by trained staff following the manufacturer’s instructions. For severe scaling or technical issues, consult a qualified technician.
A: Use distilled water exclusively, adhere to a strict cleaning and descaling schedule, and monitor water quality regularly.
