Your Guide to Glasswasher Cleaning and Maintenance
Making sure that your commercial glasswasher is clean, safe and operating at its best is non-negotiable for any food or beverage service business. Regular cleaning and maintenance not only extend the life of these invaluable machines but also ensure they perform at their peak.
As experts in glasswashing, offering an end-to-end service across specification, supply, installation and aftercare, we’ve put together a comprehensive guide to cleaning and maintenance. Read on to learn more about the recommended cleaning process, frequency, the importance of descaling and the appropriate use of specialist glasswasher cleaning products.
What should I include in everyday glasswasher cleaning procedures?
Regular cleaning prevents residue build-up and maintains smooth operation. It’s important to build these simple tasks into your daily cleaning procedures:
- At the end of each day’s service, remove all leftover debris from the interior, including the filter and the top and bottom wash and rinse arms.
- Using a soft brush and warm water or a non-foaming surface cleaner, such as our Sanitiser & Degreaser, clean the interior surfaces. Pay special attention to door seals, corners and hard-to-reach areas.
- Avoid soap-based cleaners to prevent residual soap causing foaming and poor wash results.
- Wipe down exterior surfaces with a damp cloth to maintain a professional appearance.
- Reassemble the machine and run a wash cycle to ensure no cleaning residue remains.
Why is periodic in-depth cleaning important?
Daily cleaning keeps your machine running smoothly, but periodic deep cleaning helps identify faults early, prevent serious damage and extend the lifespan of your glasswasher.
- Inspect wash and rinse arms, nozzles and filters to ensure they are free from blockages and build-up.
- Check door gaskets for wear and tear and clean them thoroughly to maintain a proper seal.
- Monitor detergent and rinse aid levels regularly.
How often should I clean a commercial glasswasher?
Establish a cleaning schedule as you would for any kitchen task. Daily cleaning should be completed after each day’s operation, while more comprehensive cleaning can be undertaken weekly or monthly depending on usage and the manufacturer’s recommendations.
Factors such as the number of glasses washed, the type of beverages served and local health regulations may also influence cleaning frequency.
Why descaling is essential
Mineral deposits can accumulate inside a glasswasher over time, affecting performance and potentially damaging components.
Regular descaling with a high-quality glasswasher descaler helps keep your machine operating efficiently. Read our detailed step-by-step descaling guide here.
You can also prevent limescale build-up by installing a water treatment system, such as a water softener, demineralisation, or reverse osmosis system.
What else can I do to protect my commercial glasswasher?
Correct usage and handling are just as important as regular maintenance.
Always load glassware correctly, avoiding overcrowding that can lead to breakage or poor cleaning. Regularly inspect and clean the filter to prevent blockages. Ensure water temperature and pressure settings align with the manufacturer’s guidelines.
Maintaining pristine glassware also requires regular renovation. Read our article, Glass Renovation: The Key to the Perfect Pint.
Following these steps will enhance the performance of your glasswasher and help you maintain the highest standards of cleanliness.
