I took a crockpot of chili to a get together. Of course on the way it spilled. Once I got to the party I plugged the crockpot in and that spillage cooked and baked on for hours! By the time I got home I really didn't want to deal with it so, I left it for the next day. Oh this was not going to be fun! I tried some dish soap and got a little off but, not too much. It was time to bring out the Jr. high science experiment! Two simple household ingredients. A non toxic cleaner that does the job of most scrubbing cleaners on the market.
Baked on chili. Not a fun thing to try to get cleaned! I tried scrubbing it with dish soap which took over surface gunk but, did little to get the baked in chili. And it's not like you can run this part of the crockpot through the dishwasher.
