Can it be unnecessaray high quality ?
I also find from our hardware store/autopart shop, Sodium hydroxide (NaOH) lye/caustic soda, and on that can it describe that its 85-100% (guess its not near 100% more like 90%) pure NAHO, Do you think it´s good enough ?
What kind is quality standard KOH, NAHO do you guys use ?
