I have put happy mouths and rubber bits in the dishwasher many times and they turn out beautifully. So do horse boots, the old Hampa kind (eskadrons and the like I do in the washing machine). I do it while my husband is at work. I work from home. I don't hide it, I just don't bring it to his attention.
Sweet. In the dishwasher it goes.
The time I forgot to run the washing machine after a load of sheets was not pretty. He put in a load of work clothes. They were sooooo unbelievably hairy. You could've made a whole horse out of the hair in that machine. Will not be forgetting that again.
