i emailed the dr. b folks to ask, and they didn't recommend it b/c of the sudsing (too sudsy).
i tried it anyway (who am i to listen to authority), and it left everything very, very filmy.
in fact, it leaves everything i use it on filmy (floors, hair, surfaces), so i rarely use it anymore.
i wish the borax/bs/vinegar combo would work for me. my dishes come out rather dirty (food spots, etc. still on them). even when i wash them 3 times in a row! i must have a lousy dishwasher!
