I just Googled and got this:
Quote:
Seasoning & Cleaning Waffle Irons
To season plug in waffle iron and let it heat up for 4-5 minutes. Take a pastry brush and spread vegetable oil, butter, non-stick spray such as Vegelene. The waffle iron should then be closed for 5-10 minutes. For proper release of waffles it is very important that the batter contains the proper amount of shortening.
Clean the waffle iron everyday it is in use. Do not clean the grids unless a buildup of carbon forms. On waffle irons that do NOT have Teflon coated grids, in order to remove carbon from the grids, disconnect, place cloth over the bottom grid, soak with ammonia, close lid and leave over night. Next day, wire brush top and bottom of grids to remove carbon. Then heat and season grids. This should not be done on Teflon coated grids. To keep carbon from building up do not use a non-stick spray but one that you can use with a pastry brush.
Note the last sentence!
