Proper cleaning and maintenance of bar glasses ensure not only the longevity of the glassware but also the quality of the drinks served in them. Always rinse glasses immediately after use. Use water and a mild detergent, as hot water can cause glasses to crack. Use a soft brush or sponge to gently scrub inside and out. Avoid abrasive scrubbers which can scratch the glass. Not all glasses are dishwasher safe. Delicate crystal glasses should be hand-washed. For stemmed glasses, hold by the bowl instead of the stem to prevent breakage. Air-dry glasses by placing them upside down on a clean towel or drying rack.
