How to prevent future water stains on glass
- You can help prevent future etched glassware by:
Increasing the temperature of the water entering the dishwasher to 140 degrees F.
- Using the no-heat, energy-saver dry cycle.
- Adjusting the amount of dishwashing detergent, you use according to the hardness of the water.
- Letting the detergent do its job unaided: Refrain from pre-rinsing dishes before putting them in the dishwasher. This not only saves water, it gives your detergent what it needs to be effective: Food to remove. Without it, the alkaline concentration of your detergent increases, which is bad news for your glasses.
