We just moved into our new house and have a dishwasher for the first time ever. Everyday plates, silverware, glasses etc. I know can go in the dishwasher. But what about my plastic cups, pots with rubber handles, plastic cooking utensils, cooking utensils with rubber handles? If I have a really dirty plate, will it come clean if on the top shelf? We bought that cascade two in one dish washer packets and we've used it once and it worked really well. I did notice that when the washing was done and I went to get the plates out they were VERY hot, hence my fear of the plastic cups, rubber handles etc. I'm just scared of ruining anything.
