High-quality glasses are pricey and need to be looked after with an appropriate level of care. This is the case whether you're in Berlin, London or Singapore. Since a good, clean glass plays such an important role, hotel, restaurant, bar and café operators all want their valuable glassware to last as long as possible, for them and their diners to enjoy. To achieve this, you need to manage your glassware professionally and you should follow the following seven tips.
Much is demanded of glasses used in food service and they are washed several times a day so they should be high quality. This reduces the risk of glass corrosion and significantly lengthens their service life.
Water quality is an important factor in the dishwashing process. Water that has not been properly treated for dishwashing leaves a grey film and limescale deposits on glassware, even after an intensive wash cycle. Optional water treatment modules on professional dishwashing machines can avoid this. Click here to read about how a reverse osmosis system works.
When you are placing glassware in the rack, think about how to stop the glasses from clanking against each other as the water moves. This can prevent minor damage or, in some cases, breakages. The best way to protect against breakage from mechanical stress is to use racks which securely hold the glasses in place. Wine glasses should be placed at an angle in the machine so that water does not remain in the concave part of the foot after the cycle.
For delicate glassware, the dishwashing machine should be set to between 60° and 63° (according to DIN and VGG) and, where possible, a gentle cycle. At higher temperatures, glasses may become cloudy or suffer other kinds of damage after prolonged use. You should also use a specific glasswashing detergent and remove the glasses from the dishwashing machine as soon as the cycle finishes.
Wash cycle times should be as short as possible. The shorter the wash cycle, the less energy consumed. That is not all, though. Short, efficient wash cycles also reduce wear on the washware. All of this pays off and contributes to improved profitability.
An integrated water treatment module will remove all the minerals from the water (as well as bacteria and viruses), providing the highest standard of pure water to rinse your washware. Pure water is a prerequisite for sparkling, spotless and hygienically clean results. This way, glasses and cutlery no longer have to be polished by hand – saving time and money. Polishing with a tea towel is unhygienic and therefore not to be recommended anyway.
Even when clean, the pores in glass are quick to absorb smells from their surroundings. If you do not have an odour-neutral place to store your glassware, you should give it a quick rinse with water before use.
