So I’ve experimented on 3 fences and about to try a deck and this shit seems to be the end all be all to the lazy man’s method. Scrub off organics, wet it and forget it. I get it pretty damn cheap from a local solvent distributor, he will give me barrel price for anything over 5 gallons. Seems to be way more effective than oxalic without the damage of SH. Can someone tell me why this is probably the worst decision?
