Can you just put it down the drain a bit at a time over a few days? It’s a drain unblocked after all.
Not sure where you’d stand on that.
That's 'Milk stone' fluid, I think - a dead cheap source of phosphoric acid.Isn't it used in dairy's for cleaning the stainless equipment ?
It's also used in making biodiesel, there's forums for that and someone might take it.
I guess that is an alternative to rolling the wheat?
Yes indeed; might be OK for stripping the paint off doors, but not very much else. So soap makers, anodisers and dairies may use it, but not out of the garden shed.No company running by the book with a quality control system in place will have it - there's no certainty in what it is, no paperwork, no traceability.
Master chef?Add 12 ton of wheat to feed wagon, add something like 400kg of caustic soda and set it mixing, then add about 3 ton of water, the reaction of the water and caustic breaks down the outer coating of the wheat. Leave it mixing for 20 minutes or so then empty out and push into a heap, leave for 24 hours in the heap then level it off and run it over to make sure theres no lumps.
Correct, caustic soda when hot is used to CIP or"clean in place" dairy equipment. Nasty stuff. Will eat holes in aluminium in minutes, your hands or anything organic will just turn to mush. As someone else said at the proper mix and temp is very good for cleaning anything. Add it to hot water and stand well back - if in doubt about its potency, it should boil the water, create a horrible gas.Isn't it used in dairy's for cleaning the stainless equipment ?
you must have a tough Budgie ,,,Its good stuff for unblocking the cludgie
its a bummer when the log wont go round the p trap
That means it's carbonated, so it's practically useless as proper NaOH.@a111r , didn't know about the biodiesel folks, I'll explore that. It has been well sealed, but because it also adsorbs water, it's no longer powdery, but just one solid lump.

I suppose the inner core could still be OH rich, so smashing it up and leaving it would work.@a111r I'd forgotten about CO2 reaction. I reckon it could well be a mixture now of carbonate with some hydroxide still present. Short of bubbling CO2 gas through it, is there anyway to try and ensure that all/most of it is transformed to carbonate? Dissolve it and leave it in a big shallow tray and reduce global CO2 levels . Re safety, yes, I worked with highly concentrated nitric in the past, so very PPE orientated.
Yes, carbonates will be less soluble. Whatever composition it has now, it's really solid; breaking it is a lump-hammer and improvised chisel job. I did note that you can convert hydroxide to carbonate by reacting it with bicarbonate, which would certainly be an easy way of making it less hazardous.I suppose the inner core could still be OH rich, so smashing it up and leaving it would work.
IIRC when carbonated it may be quite hard to dissolve.
