Is there burnt food on your glass casserole dish?
It often happens with this kind of Pyrex oven dish.
If you are making lasagna, for example, there is a chance that burnt food will stick to it.
The trick to cleaning the dish easily is to use an aluminum scoop:
1. Put water and washing up liquid in the burnt gratin dish.
2. Take a used aluminum ball.
3. Rub with on burnt food.
There you go, the burnt food is gone without much effort :-)
This trick is a great way to reuse aluminum foil instead of throwing it away.
