This thread has definitely helped me get motivated -- now that I have a bunch of dirty ponies on my kitchen counter I have to clean them!

I don't plan to make the dishwasher thing a part of my normal routine -- it was just a little experiment. I think it was a big success for me, but again I will stress that I used really, really simple dishwasher soap with very few chemical ingredients (honestly, the stuff I use has only about three ingredients total). So if one were to repeat my experiment with whatever dishwasher soap one has lying around the house without looking at the ingredients, there could be drastically different results!
Also, the dishwasher pretty much just removed the top layer of dirt from the ponies (and any dirt that was inside -- though that sea pony is still pretty dirty inside!), so I'll still have to magic eraser them.
