Question 1: What causes stains on glasses in the dishwasher?
Answer: Stains on glasses in the dishwasher can be caused by several factors, including hard water deposits, mineral buildup, detergent residue, and etching. Hard water contains high levels of minerals like calcium and magnesium, which can leave white spots on the glass surface. Mineral buildup occurs when these minerals accumulate over time, causing a cloudy or hazy appearance. Detergent residue, if not properly rinsed off, can also leave marks on the glasses. Etching is a chemical reaction that occurs due to the harsh alkaline nature of dishwasher detergents, resulting in permanent cloudy or dull spots on the glass.
