I find paint stripper doesn't work as well as it used to - possibly modern paints are different, possibly modern stripper is feeble, either way it doesn't give a clean metal finish.
I use an angle grinder with a wire brush - having a wheel brush gets you into corners better than a cup, but either (or both!) will work without chemicals. Dust and noise are the down side...
