can you not fold it into the oven and bake it? i got mites, so i may overdo it now. i usualy soak in the hottest water possible for at least a few hours, then soak it in hot hot bleach water. 10% bleach. then soak again for a few hours in the hottest water, and then rinse it very well. if i can fit it into my oven and it is oven safe i put it in there on 250. i put a lot of stuff in my dishwasher, plastic and ceramic things. i run it twice once with bleach and then once to rinse well. if it is painted it may come off over time so make sure it is dishwasher safe.. use a small test peice or somtthing.. like i said i may over do it a bit, but i will not risk mites again. i like dishwasher things, cause i can do those every week.
