I searched a 1/2 dozen threads as I assembled mine.
The prevailing theory is to use vegetable oil, or "PAM", and I saw a few guys mixing THAT with some good old bacon grease for flavor (or nostalgia) . . . If you have some sitting around.
If you DO run out and cook a pound of bacon just for this preparation, let me know, I love bacon.
Of course, FIRST clean all your cooking surfaces, I ran mine thru the dishwasher . . .
One Army Vet suggested using a paint brush, and just COAT EVERYTHING on the INSIDE surface: the burners, the heat shields, the pan, UNDERSIDE of the lid . . . EVERYTHING.
Don't sweat the side burner.
Then turn her up to high until she squirms & spasms, then AFTER she stops smoking, settle her back down to a simmer for 15-30 minutes, for some after-play. . . . ;) (If only women were so easy to please.)
OBVIOUSLY: MAKE SURE you don't have any large puddles of oil/grease pooling BEFORE you light 'er up, unless she enjoys fireworks.
(Some like a little slap here & there, or a tug on the hair . . . )
Mine's stainless, so I'll coat the outside with WD-40 before I settle her down for a smoke and revise the "hunny-do" list.
