I'm sure you are not going to use pressure washer for this :D
I remember how angry my father got when we found out that my brother used his non-stick pan. Non-stick pans cost a lot which means that he was the only one in our house who could use it. He is the cook of the family so I never really had a problem with that rule. But my brother decided to cook some eggs and he use my father's non-stick pan and did not wash it right away so some of the egg whites got stuck in the pan. Good thing he knows how to easily clean it!
