Cleaning burnt beans stuck to pot?
You can either add a lot of vinegar (to get above the problem area) -- or
you can try to displace the vinegar so you don't need as much.

Find a smaller pot and fill it with water and set it in the center of the pot to clean, and then pour vinegar between the two pots (or pot &amp; item).

Although I said 'fill it with water', you only really need a little bit more than what you need to keep it from floating once the vinegar is in there.

If you don't have a suitable pot, look for anything else that you can use that is heat safe, non-reactive, won't float (in that amount of vinegar), and will fit inside the pot.

And if you're using an anodized aluminum pot, check the bottom for scratches -- odds are they'll oxidize over time (a white powder forms), and if you have a lot of scratching, you might not want to give it an acid bath.
