Got this pan to replace another non-stick pan to which food would stick . . . even with oil/spray.  Have used this Blue Diamond pan a couple of times now, and it cleans up perfectly.  The directions say to use oil or butter but not cooking spray, so we used a small amount of olive oil the first time we used it.  The second time we used it, we didn't add anything, and the eggs came out perfectly and the pan wiped clean.  So glad we found this pan that's tough and doesn't add chemicals into our food!
