One of the most common causes of glasses turning white after washing them in the dishwasher is hard water.
Hard water contains higher levels of minerals, especially calcium and magnesium, which can cause a number of problems, including whitening of glass surfaces. If you notice that there are white spots and streaks, these are usually due to the hardness of the water.
Hard water can be corrected with a special water softener, conditioner or filter. These devices remove calcium and magnesium particles and can often be adapted to remove other potentially problematic water contaminants.
In older dishwashers, pre-rinsing was essential for thorough cleaning, but now it is not required. Modern dishwashers are designed with energy and water efficiency in mind, so pre-rinsing can actually cause problems like a white film on glasses.
The reason for this is that most rinse aid products contain phosphates, which are the main causes of white spots on glassware.
To avoid this problem, you can try to find a phosphate-free dishwasher detergent or choose an appropriate program to set the dishwasher to.
Explore the functions and wash cycles to choose the one that is more suitable for your dishes. Most dishwashers even have a glassware wash program, so you can enjoy crystal clear, sparkling glasses quickly and easily.
