In that regard the bears that ‘did’ this cabin tried, besides oven cleaner and spray foam, Aqua-Chem (the nasty blue formaldehyde laden toilet chemical), fire extinguisher, PAM, and bunch of other stuff. I have seen nothing that bears won’t try including two-cycle oil, Blazo (white gas/naphtha), starting fluid (ether; that would have been fun to see perhaps!).
