I think I will just soak the parts in naptha until I get the worst of the grease off, and then sandblast them. I just can't see any way of getting some of that baked-on dirt/grease off without blasting it.
Try some engine degreaser , I bought some by accident , (wasnt looking at what I picked up) , I did finally use it a couple of weeks ago on a 68 form S front end thats been laying untouched in an old trailer box , worked fantastic , just hosed it of --------------
