Mixing wasn't an issue for me. And the liquid never goes bad or weak...just cover and bring out for another day.
No fumes as well. I just stuck the bucket just outside the garage door...even in the rain. No smell. Especially not bad stuff like brake cleaner.
I had the bucket and battery charger. the jugs of caustic soda were cheap and the rebar 15 bucks, maybe.
I grow a lot with organics and use molasses. It goes bad very quickly and I am not sure how safe it is breathing that stuff or even handling it months later..does it go toxic ? i where latex gloves and a mold rated mask as precautions, but the mold is rather solid and not powdery so it does not become airborne during removal.
lastly, it takes far too long. We cleaned up a bunch of nasty parts very quickly...TRUE BUT MY POINT OF THE THREAD WAS I WAS IN NO RUSH FOR MY PARTS.
