I have three bottles of Ferric Chloride that are used and at least 10 years old. One of the bottles has a lot of gunk at the bottom, the other two lesser amounts of gunk, but there is a layer left on the bottom. I basically decanted them, but I didn't have to do anything, the gunk just stayed in the bottle. From a previous thread, I find I can reactivate it by adding hydrochloric acid. Do I need the gunk at the bottom to reactivate the Ferric Chloride? Will Muriatic acid be fine? Mikek
