Who has tricks for removing 50 years of crud off the bottom?
I started with power washer, then putty knife, then angle grinder with wire wheel, then angle grinder with flapper wheel for paint prep.
Any other creative ideas? I am old and don't have the stamina I used to.
I'm to the point where I think the frame must come off to do it right. Until I get the dice to do that, what makes it easier?
Thanks

Diesel fuel brushed on the crud and let set for 24 hours, then scrapper. Maybe enough diesel to soak all the way in.

Everything you have done. I went through two of these:Red Devil 6291EZ 11-In-1 Multi-Purpose Decorating Tool. Plus a lot of time and effort

Two words, heat gun. This is what everyone doing this is using to heat the undercoat for easy removal.

My car was fairly clean when I started doing the bottom. I used a scraper first to remove any remaining undercoat. I cleaned any residue with gasoline. To remove any rust or paint I used a hand drill and 2 different 4" fiber type wheels. The coarser one I bought at HomeDepot and the finer one which was made by 3M I got at Walmart. These wheels work 10 times better than any wire brush. The finer one is like the 3M Scotchbrite pad material. Here is a slide show of how good they work.

When I found out there was no way to get the new pre-bent fuel line up over the rear cross member I decide to jack the body up off the frame one side at a time and put the new fuel line in and replace all the body mount bushings and bolts.

I will try the fiber ones. I've not used those before. Your car looks great.
