Just a precautionary heads up to fellow forum members about handling Starsan liquid concentrate.
First it contains 50% phosphoric acid. Mineral acids like sulphuric, hydrochloric, and phosphoric acid are very aggresive corrosive chemicals.
Why am I saying this? Story as follows...
I keep my Starsan in a spare room with other brewing kit in a resealable bag on metal mesh racking. The other day I noticed the bottle had fallen on its side so I righted it. Two days later I wondered what the tiny pool of liquid was on the top of a can of LME. I then found out. Because the bottle caps weren't on completely tight and the bag wasn't sealed properly a small leakage (say about 10-15 cc total) had escaped. The damage was etching of the metal rack, eating into a cardboard box, and, surprisingly dissolving the carpet which fortunately doesn't matter too much. although there is now a hole in it.
So lesson learned. I will now ensure the bottle is always upright, caps properly on, and it is stored in a leakproof container.
And finally do not get this stuff near your eyes. You may lose your sight. :-o
