How to Clean a Burnt Pan

I have been horrible about burning supper lately!  Between trying to nurse the baby, welcome home hubby, take care of a potty-training 2 year old, and who knows what else, my scatter-brain forgets sometimes that dinner is burning away on the stove!  But I've become a professional at cleaning seemingly hopeless pots and pans!  Take for instance the pot in the picture below.  I seriously thought it was done for.  But as you can see in the "after" picture, it's as good as new.

It's called Bar Keeper's Friend, and it be found in the cleaning supplies aisle at Walmart or the grocery store. In my experience it has cleaned anything and everything no matter how hopeless it looks.  Some things require a little more elbow grease than others, but it will still clean things I would otherwise have to throw away.  It costs around $3.99, and it is well worth the money for the headache it saves me. 

What's your secret weapon?
