SH, HMMM!!!!. Over the years, the common way to prep a stone was to heat some crisco up and dunk the stone in it. I assume that isn't the proper way to do it?
I have use everything that I could lay my hands on in elk camp when I didn't have the proper stuff, even spit.. Most of my stones are +30 yrs old and seem to still work. I can see how one could clog one up though.
