I've tried boiling the pot with baking soda water but it's still stuck.
Any other ideas for how I can get the 1 inch thick layer of burnt sugar off the bottom of my pot?
Just wanted to say thanks Amcal, husband burnt chocolate to bottom of pan, really bad, solid black mess, even steel wool not moving even the top of it. I boiled vinegar in it, and added our home made dishwasher powder- bicarb, salt and citric acid. As you described, I simply lifted the black burnt yick off to a beautiful stainless steel finish below. Took all of 5 minutes, Thanks again.
