Never polish glasses again
Clean rims, no streaks, spotless: with the right dishwashing machine, everything is crystal clear
Anyone who works in a restaurant will know the problem: dirty glasses go into the dishwashing machine and fail come out clean again after the wash. Sometimes water marks appear on the surface or milky smears along the rim.
It is clear that a glass like that does not belong on a restaurant table or behind the bar – it needs to be polished or perhaps washed again. The dishwasher, which was supposed to reduce your employees' workload, has ended up increasing it. That's not only annoying, it's totally unnecessary. There are professional solutions on the market which will ensure that ‘clean’ washware really is hygienically clean. Without having to polish it. It's the stress-free option. After all, there is already enough to do in the kitchen.
Soft water is fundamentally better for dishwashing machines than hard water. Hard water contains higher levels of calcium and magnesium, which can lead to limescale build-up in dishwashers and increased detergent consumption. But if the tap water is hard, you don't have to just stand by and watch as your pipework and tubing become blocked with limescale. This is when it makes sense to use a water treatment system in your dishwashing machine. Dishwashing machine manufacturer MEIKO offers a reverse osmosis module for its professional dishwashing machines for food service. Simple and easy-to-use water tests can give you a quick initial result showing water hardness or you can obtain information from your local water supplier.
For clients who want their glasses and dishes to sparkle, improving the water quality is essential – and that calls for demineralisation or osmosis.
Water does not always behave the same way when we clean with it. Some of the minerals it contains can inhibit performance by leaving those familiar ugly and unappetising smears on cutlery and glasses. In dishwashers they may deposit a fur commonly known as limescale.
Water that leaves no residue with a reverse osmosis system
A reverse osmosis system will remove practically all salts from the water. That results in no residues left on glassware. The system uses high pressure to push the water through a membrane that filters out unwanted salts and then transfers the water to the dishwashing machine. More information can be found here.
A high-quality glass can survive around 1,000 washes, according to Klaus Völkner at Stölzle, a glass manufacturer. But, at some point, even the best glass will give up the ghost – and glass corrosion can occur. This damages the surface structure of the glass causing a cloudy effect or even tiny cracks. Getting the longest possible service life out of your glassware requires washing with the optimum combination of water, temperature and detergent. This is why professional suppliers set up their glass dishwashing machines onsite at the customer's premises. They test the water and provide recommendations on detergent and temperature to ensure that the machine delivers the best possible results. And that in turn also increases the service life of their glassware.
