I have been for years putting a ‘tiny’ amount of bleach into glasses, coffee mugs, vases then fill with water, to be rid of stains. You do not need a ‘dollop’ and takes not very long to then wash as usual. I have no dishwasher and I always put a drop or two in the sink when doing dishes. Keeps the dish cloth white plus the white drain pipe nice. Great for grease to.
