i have already tried the steam cleaning. it takes off the real loose stuff (at 200*) but not everything. this stuff is on there!
mix some gas and diesel up in a container and pour it all on the frame with the crap you wanna take off. let it sit over night and watch it fall off with a pressure washer! or go buy a box of brake cleaner and spray the frame crap, it will instantly lift it off the frame so you can wipe it off or scrape it but brake clean gets expensive lol
