IDK about cast iron specifically but usually cleaning off old wear-and-tear on vintage collectibles devalues them. But recall these BS&R pans aren't really valuable from a collector's perspective and people refurbish them all the time.
Of those pans, the 10" skillet had by far seen the most use. Not rusty but really gunked up. Unfortunately I didn't take proper "before" pictures but I'll tell ya, there was so much buildup on the bottom that it'd completely buried the heat ring. Then the outer sides had thick, pebbly buildup.
I tried the steel wool and soap but barely made a dent. Switched to using an old utility knife to cut and scrape the stuff off. Made better progress, got rid of the stuff around the heat ring and some of the stuff on the sides. But still, it was going to take forever.
Ended up using a 3" crimped wire wheel brush with a drill. Here's a pic after my initial test to see how'd it work. The streaky lines in the cleaned part, that's part of the remaining seasoning.

This pic also shows more of the rock-hard buildup I was having to deal with, after some removal already...

I only had a little time here and there to work on it, especially since I was limiting the duration of each session to avoid burning out my drill. And some of this stuff would take minutes of concentrated action from that wire wheel before it would come off. But as I made progress, it was looking amazing as bare cast iron...

But I still had a ways to go. There was still some stuff on the bottom inside the heat ring area, and about 1/5 of the outside still looked like this...

And the inside had this thick ring that I hadn't even tackled yet...

While meanwhile I'd already worn out one wire wheel, was having to start another...

This weekend I was working on it again and tried removing some of that inner ring. It was just as tough as the outside part! I was like, "at this rate, it's gonna take another month or so just to strip this thing..." So, I decided to try the self-cleaning oven trick. Besides, my oven needed some cleaning anyway...
The self-cleaning cycle runs at about 800 degrees for four hours and breaks down anything organic. And it worked amazingly well! Here's it coming out of the oven; the brown stuff looks like rust but it's actually the burnt seasoning...

While the sections I had already polished clean remained pristine...

Some soap, water, and steel wool removed it but there was still a dull grey residue with hints of brown. I hit it with the wire wheel and it came right off easily. I was able to clean the entire pan in less time than it'd been taking me just to work a small section...
So next was reseasoning it. I'm using the flaxseed oil method I mentioned earlier, though this time I'm baking it at 500 degrees. I've done three coats so far and plan on at least eight. I'll save any more pictures until it's done...
But this has been so easy, using the oven self-cleaning method. The other pans, I had planned to mostly just touch up those, but now I'm thinking of treating them like this one, strip them completely and reseason from scratch...
Remember the gunky old pan I posted earlier? It now has 8 coats of seasoned flaxseed oil and is done. It turned out beautifully, though not perfectly... The shine on these is not fresh oil, that's the baked on seasoning, perfectly dry...
You may notice some spots and stuff on the cooking surface. They are entirely cosmetic and have no texture; the thing feels smooth as glass. What happened? Two things...
The lighter spots, after cleaning it to bare cast iron I put it on the stove for a minute to dry completely. At the same time, The Wife was cooking a batch of her stinky chicken wings (one of the like only three things she knows how to cook). They spattered a little bit on my pan and left those stains, wouldn't come off...
Then those darker patches - when seasoning, you first apply a layer of oil and then you wipe off the excess. You really have to go after it, wipe it as dry as you can. On my second round of seasoning, I didn't wipe it well enough and those dark patches are the result, excess oil pooling up. But again, entirely cosmetic. This thing is like twice my age and now it's like a new pan.
