    Hi Debbie,

    You might try white vinegar. Or another way is to try CLR (calcium, lime, rust) acailable at diy stores.

    I've heard that you can use denture tablets from the dollar store to remove hard water stains from glass.

    Another vote for vinegar then CLR if that doesn't work. :)

  • Vinegar should do it. If they are tough deposits, you may have to scrub with a plastic scrubber.

    Hi DebbieS,

    I have a similar issue and decided to check out the options given to you so far. I definitely will try vinegar, but when I looked up if CLR is safe on glass, I found that the manufacture says not to use it on glass because it's corrosive. I thought that would be good for you to know. I'm going to try the white vinegar. Wishing you the best.

    Hello theCLR, lime away, whink cleaning solutions will help descale your cup.

    I recently used Whink and it was by far the easiest experience removing hard water stains. I used it on my hot pot— crusty bottom interior mineral build up and on the underside of my kitchen faucet where the aerator gets crusted and clogged. It worked effortlessly and quickly. I hope this helps!

    First, add warm water to the Pyrex. Add an unused dryer sheet to the water, then let it sit for around 15 minutes. Dump the water, then wipe the greasy or caked-on areas with a wet sponge. Just make sure you clean the dish with soap and water when you're done.

    Hi DebbieS, the easiest way to remove hard water stain is with vinegar, fill the glass with vinegar and let it sit for about 1-2 minutes, rinse well and hard water marks should be gone! Repeat if necessary, also , keep a container so you can reuse the vinegar on other projects. Hope this helps you out!

    try soaking it with vinegar and water mixture. Use a toothbrush to scrub off the hard water stains. You can also try baking soda
