Why Your Dishwasher Leaves Your Glassware Cloudy

 

When you put dishes through the dishwasher, you expect them to be more clean and shiny. After all, that’s the sole purpose of this convenient household appliance. Unfortunately, it’s not uncommon for dishwashers to leave a cloudy layer of residue on glassware and other dishes.So, what’s the reason of this phenomenon and how to prevent from it?

Reasons:

1) There are two primary types of dishwasher-related cloudiness: film buildup and etching. The easiest way to determine which one is responsible for your hazy glassware is to rub the tip of a needle or pin against a glass to see how it reacts. If the glass scratches with a noticeable indention, its probably etching. If the surface remains intact, its probably a film buildup.

2) Film buildup is typically caused by water hardness (AKA heavy concentrations of minerals and chemicals in the water). When the water dries, it leaves behind a film consisting of compounds like calcium and magnesium. Detergent and water alone isnt enough to remove this film; therefore, they must be re-washed by hand.

3) Food may also contribute to film buildup, especially when it contains protein. The compounds in the hard water connect with protein (eggs, meat, cheese, etc.), resulting in a thicker and more stubborn film.

Ways to solve problem:

 

1) An alternative method involves placing a drop of vinegar on a cloudy glass. If the area is clean and clear when the vinegar dries, it’s film buildup.

2) If you believe film buildup is to blame for your cloudy glassware, try adding ¼ cup of white vinegar to your dishwasher. This will neutralize some of the hard water compounds, preventing them from sticking to your glassware. You will find that your glassware became more transparent and shiny.

3) There are several different things you can do to prevent the etching of glassware, one of which is to use less detergent. Most people blindly pour detergent into their dishwasher without measuring it beforehand. In doing so, there’s a greater risk of etching. Using just half of the recommended amount will clean your dishes just as well, and it may solve your cloudy glassware problem.
