The etching will build up slowly over time and may first appear to be an iridescent color such as blue, brown, pink or purple, according to the University of Nebraska Cooperative Extension website. There are, however, certain things you can do to reduce etching of your glassware.
Things You Will Need
-
Check to see if your area has hard or soft water. You may need to adjust your dishwasher detergent according to the package directions or switch to a different type. The package should tell you whether you need to use more or less detergent, depending on the softness of your water. Less is best. Using less harsh detergents designed for softer water can reduce etching, reports Pure Water Products.
-
Check the water temperature on your hot water heater. You should always wash dishes in water that is 140 degrees Fahrenheit or below. Using a water temperature that is too hot can cause etching.
-
Purchase a rinsing additive and fill the appropriate dishwasher receptacle with it. If you do not have a receptacle to pour a liquid dish-rinsing agent into, you should purchase one of the small baskets that hold rinsing additives and hang it in the back corner on the lowest rack in your dishwasher. The rinsing agent will help the sheeting action of the water and reduce etching.
-
Switch your dishwasher to the no-heat or energy saver cycle. This will cut down on etching and also save you money on your electric bill.
