White spots left on dishes by dishwasher?

White spots on dishes after being washed in a dishwasher are usually caused by hard water. Hard water contains high levels of dissolved minerals, such as calcium and magnesium, which can leave behind a white film on dishes when the water evaporates.

There are a few things you can do to prevent white spots on dishes from hard water:

* Use a rinse aid. Rinse aids help to reduce the surface tension of water, which allows it to drain off dishes more easily and prevents it from leaving behind water spots.

* Clean your dishwasher regularly. limescale can build up inside your dishwasher, which can contribute to white spots on dishes. Clean your dishwasher regularly to remove limescale buildup.

* Adjust your dishwasher's settings. Some dishwashers have a setting for hard water. If your dishwasher has this setting, turn it on to help prevent white spots.

* Use a water softener. If you have very hard water, you may want to consider installing a water softener. Water softeners remove dissolved minerals from water, which can help to prevent white spots on dishes.
