This is sort of a shower thought because this morning I was using some shaving cream and I thought, if it turns out in 5 years this was giving me cancer, I wouldn’t be surprised.
Comes out a goo, ejected from a can with force, immediately becomes a foam?
Do you have anything you use that you think might be too good to be true?
It’s an electric heating element and a fan, same as a convection oven except it exhausts rather than recirculates the air. Any issues beyond the grease buildup you mention would apply to any electric oven or toaster.
