Hi Deejay, we're sorry to hear about the trouble you've encountered with your sheet pans. One proven solution to deal with difficult stains and food particles is to do the following to your sheet pan:- Sprinkle baking powder or an all-purpose household cleaner on your pan.- Then with a wet paper towel, rub the cleaner into the pan. - For more difficult spots, crumple up a piece of aluminum foil and rub against those areas. - Afterwards, hand wash your pan(s) in warm water and soap.Good luck! If you continue to run into any trouble, please feel free to contact us at artisan@vollrathco.com.

We are glad to hear that the pans have worked well for you. Be sure to check out our new 1/4 size 2 pack made of the same great quality on Samsclub.com
