If you are a dummy like me with dish-washing and suffer from the incurable and extremely fatal condition of procrastination-after-eating-food disease this tip is for you all; students especially. When you eat something like an oatmeal cereal or rice and let the bowl dry for a good long time just because you are lazy, the food becomes so hard you will wonder why you use expensive cement instead of oatmeal or rice.
All you need to do is pour in some water, and microwave it so the sticky part loosens and scrubbing t off the utensils becomes easy. You can also pour boiling water into the bowl if you don't have a microwave or if the dish is not microwave friendly and allow the water to stay for a while before scrubbing it off.
Oh! and coming to the oatmeal cereal instead of cement, builders were probably worried about hungry people who live inside the rooms.
