PamperedGinger said:Funny you should mention this. I was having the same problem, but not only on my batter bowls. I have a dishwasher and I wash everything in there. I started having problems with white residue on everything. First I ran my dishwasher SEVERAL times with just vinegar to get rid of the soap residue. Then I changed from the Costco brand of liquid to Cascade Complete and use 1/2 of one of the 2 dispenser cups. Everything shines...included my batter bowls.
