The past few months I’ve been using white distilled vinegar for my dishwasher rinse aide. It’s great because it’s non-toxic, completely natural, and it costs a fraction of commercial rinse aides. It should actually make your dishwasher last longer as it removes mineral deposits so nothing will get clogged with nasty hard water. The best price I’ve been able to find on distilled white vinegar is at Costco. They sell a box that has two gallons in it for about $3.50. Try it and give me some feedback.
