burned carrots in a good pot and can not get it clean on the bottom...hate to trow pan out.
Boil some vinegar in pan
baking soda & salt in boiling water...as it boils scrap bottom w/ spoon, wooden spatchula, or metal one depending on what the pot or pan is made of
I have always boiled the pan with some washing powder for a good hr or two (I have been known to let this boil dry, oops!) - leave it long enough and this will easily solve it.
