Best way to clean hard water residue off of glass?
February 19, 2020 12:15 PM Subscribe
I live in an area with hard water. Just in the course of washing off my glassware with it, it accrues mineral deposits from the water. What's the recommended way to clean it off so that it looks clean and sparkling?
Sometimes, the hard water will actually etch the glass (usually after a long time without cleaning them off), in which case you are SOL.

LemiShine! When I used to live in Pennsylvania we had terribly hard water and all our glasses were cloudy and awful. One run with LemiShine and they were totally clear. It was amazing.
(I'm pretty sure the stuff I've linked to is the right stuff--they've added a bunch of products since I had to use it, because the water in Alaska is not as bad as Pennsylvania, and I think my dishwasher is better too.)

Yep, that granulated LemiShine stuff does the trick. At my house, their rinse aid does not help with the hard water and makes the whole dishwasher load smell like wet dogs but this is almost certainly not the universal result!

Thirding LemiShine. We have hard water too and it works like a dream.
I have read that Lemonaid Kool-Aid mix will also work but have not tried it.

You can buy 5 lbs of granulated citric acid on Amazon for $15. I'm pretty sure that's what is in the lemon stuff. Put a tablespoon in your dishwasher, or more if your water is harder. You can also mix it up in the sink and soak any glasses with severe deposits.
Do not do this with metal things, it ends badly.

We use Finish Hard Water Booster -- that page says it contains citric acid.
And yes, I'm also losing the silkscreen designs off my pint glasses...

Seconding white vinegar. We just pour some in the bottom of the machine before we run and it works wonders.

You've got good suggestions for the dishwasher itself, but water softening equipment added to your water supply feed is good too. You have to add salt to the softener to allow it to flush the minerals it accumulates, but bulk salt is cheap, and most systems are low-maintenance.

Nthing Citric Acid. Recently bought a fancy dehumidifer and the manual said to use a solution of Citric Acid to clean it, so bought a big bag of it on Amazon and damn, this stuff is magical on glass. Dilute it and swish it or use it as a paste with a brush. Got all the hard water stains off my vases, hurrah.
