Alright, i'm jumping in. Just order the 25 lbs. of Boric Acid from Dudadiesel and will finish off with 20 Mule Team Borax for the last 5 lbs.
By the way, has anybody been to Death Valley NP and seen the 20 Mule Team story with the how they got the borax out the valley. It must have cost a lot for borax back in 1890's because that was a lot of work to get it out there.
