I spent an hour with a wire cup on my 4" grinder and got the frame clean back to front. Once that was done I sanded the surface rust and cleaned it thoroughly.

With the frame cleaned I moved on to the floor pan. I spent a while with a course wire brush and Scotch Brite getting the years of accumulated dirt cleaned away. After blowing the remains clean I blasted it down with brake cleaner.
