These Dishwasher Additives Remove Gross Hard Water Stains

I love having deep royal blue glassware, but hard water stains look especially gross on dark-colored glass. Fortunately, detergent manufacturers are here to save us all from their new phosphate-free formulas with improved versions that pollute the environment less, but pollute our dishes more. Our sparkling colleagues down the hall at Consumer Reports learned that additives meant to clean up this gross residue actually work.

The three additives that they tested all performed well, though one
(Finish Power Up Booster Agent) required an adjustment to the directions, since it didn’t work very well in the pre-rinse cycle. Glisten Dishwasher Cleaner & Hard Water Spot Remover and Lemi Shine Original both performed admirably.

If you’re trying to shine up your dishes for use on the Thanksgiving table, remember that not all dishes and serving pieces can or should go through the dishwasher on a regular basis: be careful with china and crystal, for example. They won’t explode on the first washing, but repeated trips though the washer can damage the dishes.

    i don’t have a problem with spotty glassware – i don’t really use many actual glasses. but my plastic started getting a white hard water film after the new detergent rules. i find sprinkling a bit of barkeeper’s friend into the dishwasher right before i run it does away with the majority of this

      I have the white hard water build up on my plastics. You just pour some of the powder into the bottom of the dishwasher? It doesn’t hurt anything else?

        i don’t use it every time now that i have a newer dishwasher that’s designed to work with the new detergents (i really don’t know how it makes a difference, but it does)
        but when i have a large load of plastic food storage containers or in my old dishwasher, i would just give a few shakes of the barkeeper’s friend canister down the inside of the door right before running it.
        i was getting desperate and doing a lot of internet searches for a solution so i wouldn’t have to start hand washing my gladware. some mommy blogger site recommended it after using it on plastic baby bottles.
        for about $1 a can, it seemed worth a try. and it’s great for my steel kitchen sink too.

    I love LemiShine. I wish it wasn’t so expensive, though, like $3.50 for a small canister that lasts for about half of a small detergent box. It’s the only thing we’ve found that consistently gets our dishes clean and free of the white rings.

    A cup of white vinegar during the rinse cycle will also take care of the hard water film on plastic/glass. Not sure how many washes you get out of any of these additives, but a gallon of white vinegar at $2.89 for the store brand will net me 16 washes, and I can’t imagine getting much more than that out of one bottle of Lemi Shine if it’s only 12oz. The only downside is that your dishes won’t have a pleasing fragrant smell that the additives give, but I’m all for less chemicals.
