How do you clean cloudy glass?
The answer begins with understanding what causes glasses to become cloudy: Usually a scratch-causing combination of water and detergent.
Let's start with the water. It is usually softened to make soaps clean better. And dishwasher water is heated to 140 degrees to increase its cleaning power further.
Then there's the dishwashing detergent. It's packed with phosphates to further boost its cleaning power. And then there is you and me - the user who dutifully rinses dishes and drinking glasses before loading them into the dishwasher.
The combination packs an almost too-powerful cleaning punch that can leave your glasses looking worse for wear. Don't worry - these tips can help you clean cloudy glass.
Water Stain, Hard Water Deposit, or Etching?
When the dishwasher runs, things get hot inside. Without hard-water minerals to act on, and little food waste to occupy them, the cleaning phosphates in your dishwashing detergent turn into troublemakers for your glassware.
At the end of the cycle - or combination of months of cycles - you end up with cloudy glasses that no amount of cleaning seems to coax away.
A magnifying glass, however, would reveal the truth - your glasses are etched - as in the glass surface itself is scratched. You can't clean cloudy glass with this problem.
To determine whether you're dealing with water stains on your cloudy glasses, hard water deposits, or etching, drop a bit of vinegar into the glass.
Rub it around with your finger. Drain the vinegar; let dry. If the rubbed area dries clear, the problem is likely water stains, or hard water deposits. If there's no change, however, your glassware has been irreversibly etched.
How to Clean Cloudy Glass of Water Deposits
To remove hard water stains from glasses, add an acidic rinse (such as white vinegar) to your dishwasher, and rerun the cycle with the glasses inside.
The best performing low phosphate detergents include Finish Powerball Tabs, Cascade Complete Actionpacs, and Cascade Complete Gel Dishwasher Detergent.

How to Prevent Cloudy Glasses
You can help prevent future clouding on glasses by:
- Increasing the temperature of the water entering the dishwasher to 140 degrees F.
- Using the dishwasher's no-heat, energy-saver dry cycle.
- 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.
