What can the hotel do to clean the glass?

Hotels must clean wine glasses before using them, although some people suggest washing them with warm water or detergent, depending on your preference. However, if detergent is used, the glass must be washed clean, because even a little lemon flavor or aroma similar to detergent may destroy the original flavor of the wine. When cleaning wine glasses, drop a drop of detergent on each wine glass, then gently scrub it with a clean cloth in warm water, and repeat it several times until the stains are cleaned. After cleaning, be sure to pick up the glass and put it under the lamp to check whether it is clean. In fact, there may still be some detergent foam on the surface, which is difficult to rinse off with clean water. This will greatly affect the taste of wine, especially sparkling wine glasses or champagne. The bubbles in these wines cannot be released well in other wine glasses. Drain the water immediately after washing, and the dried wine glass will be quite shiny, so that the water stains will not leave any traces. Although water stains are easy to wipe off, they will greatly affect the appearance. Put the clean wine glasses vertically in a clean and tasteless cupboard. Soda cleaning: This method is mainly used for crystal wine glasses or expensive glass glasses. Pour a little clean baking soda into the glass, and then gently shake it with warm water. Soda can absorb and remove any remaining stains in the glass. Although this method is a bit time-consuming, the cleaning effect is very good, and the glass is bright and clean without stains. Dishwasher: This method can only be used for wine glasses with short handle and low price. Dishwasher is a very effective way to clean a large number of wine glasses at one time. Pour in a little less detergent than usual, and then let the dishwasher clean the glass. Set the drying time of wine glasses to the lowest level. When the glass is dry, take it out immediately and dry it with a dry towel.
