Burnt Tea Bag in Pot?

try filling your tea pot with water and adding a tablespoon or two of dish washer powder, Put on stove and boil for a while. hope it works for you

pour bleach into the pan and let it soak. make sure to cover the burnt on stuff. Add a bit of water if needed.

I put vinegar in the teapot and boil on the stove for about 2 minutes. Then wash as usual.

try using tin foil on the spot it works scrunch it up in a ball and rub
