Drinking glasses- Is there a way to restore them?

I had the same issue it hard water that caused my issue pour some white vinegar into the dishwasher then add your detergent as usual. I had to run some of my glasses through twice to get the deposit off but I add the vinegar all the time now and it works.

Put a Cup of vinegar in your dishwasher before your run it next time and also use Jet Dry in the dishwasher.

.I use a rinse-aid type of product. Cascade is 1 brand. JET-Dry is another. Your dishwasher should have a built in dispenser in addition to the soap dispenser. Fiil them prior to washing. My glassware is always clear.

you need to use jet dry in the dishwasher and use the pods instead of powder.in the mean time soak the glasses overnight with baking soda and water.that should remove the residue, if that fails try bar keepers friend

If the film doesn't come off with vinegar, your glasses may be permanently etched with little scratches. In some parts of the country, softened water combined with dishwasher detergents that contain phosphates can cause etching. If you have softened water, use less detergent than the recommended amount and remove glasses immediately after the wash cycle to avoid the high heat of drying, which can accelerate the etching. Or use a low- or no-phosphate detergent.

You need to be using Jet Dry. It will remove the cloudiness. Be careful not to over use dish washer detergent. It can etch glassware.

You can also soak the glasses in vinegar
