Over time and likely due to the dishwasher many of the glasses in the kitchen have developed a residue on them. I’m not completely sure of the cause, and despite the streaking and fingerprint-ish look I can’t seem to wash it off. Thus, I thought it to be a mineral deposit likely caused by a combination of dish detergent and water chemistry. A bit of online research pointed me to a product called Lemi Shine (very detailed chemical info on the product here), so this morning I purchased a container and gave it a try.
Following directions on the container I first ran the dishwasher empty with just a helping of Lemi Shine to remove hard water deposits from the washer, and I then ran a load with just glasses and the product. Per the promises on the container and reviews I’d read online I expected this to clean the residue from the glasses, but it didn’t. I then ran one more cycle with more Lemi Shine and dishwasher detergent, which is the prescribed use, and this too seemed to do nothing†.
I’m going to have to try some other options and see what works. I may try some CLR, but being another acid-based cleaner I don’t have a ton of hope for it. There’s also BLC Beer Line Cleaner which is a base and might do something.
I guess I could just leave it be, but the glasses are starting to look unpleasantly grungy. The photo above shows the problem quite well, but it’s a little more exaggerated due to the glass sitting on a black background, being somewhat side lit, and a polarizing filter being used. It does a pretty good job of showing the unexpectedly streaked nature of the deposits, though. I hope I can figure out what will remove this.
† It did do one thing: remove paint from some glasses and mugs. I’d thought that all of my glasses and mugs had their logos glazed on, but after the Lemi Shine treatment I found that many of them were missing some or all of their logos. Whoops. This makes me feel really bad because I don’t like it when I unintentionally ruin things.
