. To control overspray, I still tend to spray it on a folded paper towel and then rub it all over the gaskets. I used to do this once or more a year -- until I followed lewster's advice with the teflon spray. The interval is more like once every 18 months or so now. The gaskets up under the Fantastic Fan tend to need the same treatment.
