If your pan has a sticky residue on it, this generally comes from excess oil or burnt food on the pan. We have found steel wool to be the most effecting in removing this and avoiding damage to the pan. You can also use crumpled tin foil in place of steel wool if you are worried about scratching the pan. Rubber scrapers and tough bristled brushes can also do the trick to remove this sticky substance.  Feel free to get the pan wet during the process of removing the sticky residue but do dry the pan promptly following that and rub with oil afterwards for best results.
