- The original instructions say to run the vinegar through first, and then the baking soda. When I tried it I almost missed the line that says to run them through separately, but luckily I caught it in time. Vinegar and Baking Soda will react in foam, and if you run the two cycles through together you will get foam throw-up. That's is NOT what happened here, Ellen ran them through separately following the directions. I'm just saying it could happen.
- This may be a similar case to mine...not necessarily the Barbie arm and scalp, but if there was enough residual detergent in the dishwasher the vinegar could have reacted with it causing the spew.
- The only other thing I honestly can think of is that if you're like me you have bottles of cleaners...but sometimes it's a homemade cleaner in a vinegar jug, or a glass cleaner jug. I've forgotten that the jug does not have the original contents once or twice (my vinegar jug had dish soap in it once...just about had the most interesting chicken marinade ever). Don't worry, I very thoroughly wash containers out before I put other contents in them. Anyway, perhaps there was a cleaner in the vinegar jug and not vinegar? I know it's a slight chance...but hey, it could happen, right?
