Well... I was out here in the colonies... masked and by the local home despot... and I decided to hike over to the kitchen section.
I asked the probrotradesman kitchen guy if those aluminum range filters come coated with cooking grease. He said... not as he knows for... and thinks they aren't sprayed with anything... but, might be a good idea if there was something to spray them with.
Anyway... ya, I think the manufacturers don't coat them.
