I just watched a Youtube video on cleaning oil soaked brake shoes on a '48 8N tractor. The guy was heating up the shoes with a propane torch after cleaning up the bulk of it with brake cleaner. I was getting ready to do the same thing later this week on an 8N I am in the middle of repairing. I think I will alter my plans now! Thank you for the heads up!
Maybe propane won't make phosgene gas, but I don't want to be that guinea pig.
