Since then I've been keeping track of spills, and hardly a brew day goes by without some sort of spill.
Got to love the spills when brewing! I setup my equipment in my kitchen as well. There is usually a pile of towels in the laundry when I'm done. One of my recent brew days, I forgot to close the valve on my FV. I turned around to do some cleaning and when I turned back there was a huge puddle on the floor. Luckily I only lost about a pint or 2 of wort before I noticed.
As for the OP. One thing I've noticed with pbw is it burns like hell on any cut you may have. Even if the slightest amount gets in it. It's also a bit slimey once dissolved in water, as everyone else has said.
