What do you think, does the acid´s produce a stinging smell? What do you use as your washing methode?
It's been my major concern from the start, and today I experienced it again. You have to mix the stuff and make sure it goes where you want it...
I decided on metal jerrycans as they are solid and have a tap that closes real tight... as opposed to plastic ones, and you can insert very long sprouts... the latter fit into 1 inch diameter plastic water hoses (gets the stuff anywhere, say from the bathroom to another, or tho a second canister). I use a secondary canister, a plastic one, where the hose leads in very low and horizontally, This is a 20 litre affair and it's filled with rock wool and water, just enough water so it doesn't run out (check height levels of canisters involved).
There's a plastic grid about half way up the canister, from there on it's filters for these kitchen vapor filters... you get them at amazon, they're in part white for grease and black for the rest - throw away the white stuff, you want the black active carbon (charcoal) filter, stuff it in the canister and there you go. Away from the water, on top. Understood ?
You last have to fill the acids into the jerry can of course, do the sulfuric first... if you're using 5 liters (10 l canister) , you will need a long time to get the formic inside the can, while the stuff is already reacting - this is bad, it means intense fumes would immediately rise and start going upwards to your face... wear latex gloves, a full-face gas mask and protective plastic, and do it outside. THE FUMES ARE UNBEARABLE. Be very calm when you do this... try to be godlike... thine name is death ;)
I am working on a way to introduce two plastic bags into the jerrycan, then filling the two acids into one each, later cutting the throats of those two bags - see ? Reaction starting while I'm already closing the bugger.
Then close the canister with the prepared sprout-attached-to-hose-attached-to-filter-canister, everything is of course prepared so it can be easily done... [this is all very simpl if you just use a few milliliters like in what you read online, but if you're serious, you have to make amends].
Close tight, shake-shake. Put down and enjoy. Stuff gets warm maybe 30 degrees, no problem. Tally-ho ;)
