We purchased this piece when we attended a home show between 15-18 years ago. It is the ONLY piece of bake ware (other than pyrex), that we have not had to replace. We love it! I will confess to having put it in the dishwasher a handful of times over the years - and it can make it less non-stick. I've never really understood that, but I stopped putting it in the dishwasher. After all these years, we do have a few stains, but scotchbright pads take it out if you find yourself with a few. What it comes down to is this - it's not the pan that is burned - it's the grease that was on the pan, so you can always get the stain out with a little scrubbing. I do NOT recommend uzing non-stick spray on the pan - actually I think that is part of what caused the stains.
