I don't know about drinking it Mobery... but I certainly can recommend it for removing bugs from your windshield, stripping paint, and as a sheep dip. Actually, I've used it on my dogs and they have been pest free for several years... also hairless... which is not the preferred look for an Irish Setter... Gotta go with George's recommendation...
PS Arron... The recipe sounds fantastic...I'm going shingle shopping today... is that with or without creosote??
