How do you deal with removing rusty scale from inside the semi-boxed in area in front of your spring hangers? I'm working on my '72 Charger and I'd like to clean that area up, but there's not much room for access. It looks like a wasp can get in there, but not much else.

Thanks for all the replies, it's just about impossible to reach all the surfaces inside that area. I can get 2 fingers in there, that's how tight it is. (easy now) I've used everything I had, and even made some stuff. My sander with a 1/2 x 18" belt worked the best of everything I tried. I made an attachment for a die grinder which was essentially a 1/4" rod welded into a piece of tubing with a slot sawed into it. I put about a foot of 2" or so sanding belt on it and let that flail around up in there. It must have done something, it made a lot of dust! I've ordered some of that Eastwood frame coating to shoot up into there, maybe it'll last another 47 years. By then I won't be caring much about it. Thanks again for all the ideas.

I've used both Safest Rust Remover and Evapo-Rust. 5 gallons of the former and about 30 gallons of the latter. I much prefer Evapo-Rust.
For one thing, Safest Rust Remover makes a scum with age that comes out of solution, so if it is over a year old, you may need to run it through a screen or filter. Also it seems to deplete faster strength-wise compared to Evapo-Rust. So far I have found no advantage over Evapo-Rust.
Haven't tried it yet, but I believe Evapo-Rust will work fine with a small pump and a $15 child's wading pool. Be sure to know the exact volume so you can add back distilled water to make up for evaporation. You can also keep a part wetted with Evapo-Rust by placing paper towels or rags on the part to be de-rusted and re-wetting it frequently.
You can pay no freight on Evapo-Rust if you buy it online from Northern Tool and pick it up at their store, $80/5 gallons.
Used to think seriously about investing in a sandblast set-up. Glad I never did - Evapo-Rust works fine for me. You can buy 100 gallons of Evapo-Rust for the same price of a small sand blast setup. I recently de-rusted doors and trunk lid with it.
