I am now rejecting this advice entirely, with a single caveat. Today, on the recommendation of a Pinterest article, I did a normal, greasy load of dishes and included a couple of beer glasses. BUT I added a cup of white vinegar. Just dumped it in the bottom of the dishwasher. And wonder of wonders, everything came out not just clean, but sparkling and shiny! Not just the stainless steel and plastic (which look new!) but the beer glasses as well. I promptly poured a glass of my Citrillo Blonde ale and that glass is clean. Some of you know I like my beer clear. Really clear. Well, there was not a single bubble clinging to the side of the glass, I could see clear over to the neighbors’ houses on the next street, and the head retention is just fine. Beautiful lacing intact.

Will it eventually etch the glass? I don’t know. Maybe. If it does I’ll replace it. Small price to pay for being able to stick it in the dishwasher from now on.
I’d be interested to hear what the Borg’s experience has been, if you’ve tried it.
