A dear sweet elderly lady that I know fell asleep with food on the stove. I went over to help her get all of her plants in before the freeze and noticed two really good pots sitting in the garage. When I got closer I noticed that whatever was in them had become petrified rock soldered to each pot. She was so embarrassed and told me that she ruined her two favorite pots when she fell asleep with dinner on the stove. One pot is a nice pressure cooker pot and the other a heavy duty 1 quart saucepan. With alot of elbow grease I was able to get the saucepan clean and shiny, however, the pressure cooker is proving to be quite a challenge. I soaked, scrubbed, used steel wood, used a wire brush, used commercial cleaners and managed to get alot of it but it still is not anywhere ready to be used again. Any ideas or suggestions would be greatly appreciated. I'd love to get her pots back to her before Christmas.
