Let's say a guy I know needs to get rid of some. How would I... I mean he get rid of it?
Hydrogen, Oxygen, Sulphur- can't be TOO bad for the environment if it was WELL diluted and mixed with water.... at least we're not talking Agent Orange... just sayin' ......
And, YES it is dangerous stuff (physically) ... but not too bad environmentally, kinda, relatively....you know what I mean....
