I have had a bad experience with some corn oil spray; now I just use soybean oil with a natural boar's hair (pastry) brush. Heat the waffle maker at the last moment possible. Heat turns oil into varnish. Oil the surface just before the first cup of batter. I like to scrub oil with the brush into all the dry looking areas. If your batter has 1 Tbs oil per waffle, that may be all you need for the batch. Turn off the heat promptly. I don't wash the oil out of the non-stick surface unless it builds up.

We always use a bit of that Spray on butter... You still need to lubricate it each time you lay in a waffle...
