It keeps them beautiful! I make everything from scratch for over 40 years and I have tried every brand cooking pot around and this to me is the top of the line! You will never be sorry you bought one!!!
I have the soup pot and the fry pan and grill pan
I have several pieces of Staub
I have the 4, 5 & 8 quart cocotte`s
After I wash the pot I always put a bit of cooking oil in them and wipe it around with a paper towel
