Thank you so much for the info. I, being a housecleaner took note of the uses for muriatic acid that would benefit me. I put a solution of pickling lime on a bunch of palys yesterday, it looks like snow. It was a section away from other stuff and I'll let you know what happens. And if anyone is interested, I'll post a later picture of the finger progress. It isn't swollen anymore and the scar tissue is forming around the crater, but it went all the way through all layers of skin. It looks like it's going to be a real nasty scar. Ugh. Still pretty sore too.
