Usually lasts until I kick the container over yet again
Iv had it last for a year or so then it grew some sort of gunge on the surface so guess it was past it sell by date.

Ditto here, but mine lasted closer to two years.

Have a look for Scale Clean or similar products used in the coffee trade its a lot cheaper and comes on 1kg bags and its citric acid
This site is a bit expensive but you can see what Im on about

I can't say for sure, but it is my understanding that any solution starts to lose its efficacy upon exposure to atmosphere. This applies to sulphuric and cupric solutions; I can only assume the same applies

Does anyone know how long citric acid pickle mix lasts for?
I've always used sulphuric acid for pickling brass & copper, but it comes with inherent risks associated with its use.
