Snake shedding: wart remover/salicylic acid vs lugols iodine?

One problem I’ve had with pumping is hemosiderin staining, where the iron in the blood causes the skin to darken.

I’ve read thru the "Shedding the snake" thread which advises to use wart remover (salicylic acid) to get the skin to detach and peel away, removing the outer layer stained skin.

I actually tried a small sample size and though no problems, I’m still not sold on it.

Then I searched and found that Lugols iodine can also do a very similar thing. Over time after daily application, it causes the skin to dry up and peel away taking the staining with it.

They seem to do the same thing, except that Lugols iodine is less aggressive. What does anyone think?
