How to clean cloudy glass?
The answer begins with an understanding of the root cause behind most glass clouding: Usually a scratch-causing combination of water, detergent, and you.
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 often leaves drinking glasses looking worse for wear. These tips can help clarify the problem, and provide solutions to clean cloudy glass.
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.
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.
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.Restaurant Crystal Clean: Professional Wine Glass Cleaner a try; it works wonders on removing glass clouding and reducing soap scum - no soaking required.
