I love my Pampered Chef Pizza Stone. When I got it I thought I had been crazy to spend that amount on it. Once I cooked on it a few times it smoothed right out and sealed up.
I occasionally wash it in the dishpan, I don't let it sit there but I do wash it quickly then rinse well. Dip it in then rub the front rapidly then put under running water. Less than 30 seconds I bet. Then I stand it on the drainer.
I also cook my crust half way first. I cook everything that goes on the pizza first. I use Jimmy Dean Sage Sausage and crumble it up, cook it soft, not crunchy. Then I saute the onions, bell peppers, mushrooms, anything I'm putting on the pizza in the sausage grease that's left when I dump it out. So not much at all.
I use real butter on the warm crust and sprinkle garlic powder on it then add a tiny bit of cheese to help everything stick on the crust. Then bake it until the cheese in the middle is melted but nothing is burned.
