You can wash almost anything in your dishwasher...
Like your make-up brushes, throw them on the top shelf and they will come out like new.
How about all those little action figures your little man plays with or your childrens bath toys? Put them in a lingerie bag or something like it, and put them on the top shelf in your dishwasher and wash away.
( The lingerie bag is for your protection, you don't want any little peices falling into the mechanics of your machine )
