So basically, you can pay $22 to have them mix an unknown amount of NaOH into 32oz of water, or you can buy 5 lbs of NaOH off Amazon for $19[1] and mix it into water yourself. A lifetime supply of "phurwater" for less than the price of a single bottle, without even shopping around--this was the first search result on DuckDuckGo.
What incredible crap.
