Bozz said:Another thought on soda supply.
Many cattle farmers/ranchers use soda as a feed supplement.
As a result, you can get 50lb. bags of it at most feed stores.
At both my local feed stores a 50lb. bag is roughly $20.
Certainly not a fine grain as Arm&Hammer and cheap to boot.
I have not done a side-by-side comparo with branded "blasting soda" so I can't say if there is a difference.
This is in the USA, so International pricing will likely vary significantly.
Just another option to consider, right?
