Question: is vinegar a good rinse aid for dishwasher?
Answer: First, you should not put vinegar in the rinse-aid dispenser in your dishwasher. ... It is a bit of a pain, since you need to stop your dishwasher and put the cup in just before the rinse cycle. It also doesn't work as well as rinse aid. Vinegar can be a chelator, but it's not as good as EDTA.
