I would give serious consideration to sand blasting or maybe a softer media to do the blasting.

I've sandblasted them before, but the thick baked grease/grime is hard to blast off with smaller less powerful blasters. Scraping the thick stuff off, then degreaser, then follow with a blaster & you can eat off it.

I blast everything! Scrape off thick stuff, power wash works if summer or good hose and Gunk cleaners. Then Blast. You'll have to tear down to almost every part tho, it gets into tight areas like bearings no matter how careful you are. Thick grease not cleaned off or any rubber won't blast......just get's "snotty" on grease, rubber cleans and won't get harmed. But, the rubber might be hiding rust underneath it!
