About 12 years ago, we were given a silicone baking mat (a “silpat” brand) as a gift. It came with an expanded aluminum tray to set it on when using it for baking.
Years have come and gone, and the silpat has seen better days. It’s brown and grungy now, as years of accumulated grease have finally gotten the better of it. I am going to replace the mat, but finding a replacement tray is proving harder. The only thing really wrong with the tray is the browning that happens over time as it takes on oils and they polymerize on the surface. I have tried scrubbing it but it is a lot of very slow work and it’s frustrating.
So I got to thinking about how ovens use a self-cleaning cycle by basically heating up to very high temps and turning all contaminants to ash. Would it be possible to do the same thing to this pan, using a propane torch? Or am I going to end up making this thing look even uglier than it does now?
