Cleaning Glassware
Clean glassware for wine service is essential. Wine glasses with water spots or non-smear lipstick marks at the rim will affect whether guests choose to return. Non-smear lipstick will not come off with just the use of a residential or even a commercial restaurant dishwasher. The glasses must be wiped, especially around the rim with a soapy cloth or sponge prior to placing them in the dishwasher.
A spot-free rinse agent should be used along with the normal dishwasher soap in either a residential or commercial dishwasher. Otherwise, someone will have to be assigned to wipe the wine glasses with a clean cloth sometime before reusing them for wine service.
