Hi Prima-
When I roll the Mat up- I roll the first with the seasoned side in-not too tight- then I roll the second one around the first one- I think seasoned side in as well- my Mat is not heavily seasoned- so if any shortening is getting on the back or other mat it is negligable- I always wipe down my mat with a viva paper towel- (lightly) before I start- hoping to catch any lint- dust specs etc.- doesn’t effect the seasoning-
I periodically re-season the mat- as I wash mine down with hot soapy water often-
So far so good-
