What is the byproduct of a leave-old soda acid fire extinguishera It is a crystal, such as the accumulation of the Interior A crystal inside the accumulation of the extinguisher that will not flush. This is an old fire extinguisher that has obviously been released. Is it toxic residues and how clean ita Are there chemicals that will easily remove ita Trying to understand if the residue is acidic or alkaline. * The way they used to work at a bottle of acid was broken and mixed with soda ash to produce CO2, which creates a pressure that expels the extinguishing agent. Thus I understood anyway ...

"The soda-acid extinguisher was invented in 1881 by Almon M. Granger. His extinguisher used the reaction between a solution of sodium bicarbonate and sulfuric acid to expel the water pressure on fire. "
by-products are expected to be water, CO2 and Na2SO4, ... yes, the CO2 creates pressure to remove water
Na2SO4 is a white crystal that dissolves easily in water and rinsed, non-toxic
-----------------------------------
if the deposit is white, but does not come off with water ...
theyt it is likely that water was hard, and you have a deposit of CaSO4 which will not dissolve out
--------
if the deposit is greenish, it is likely a patina of copper carbonate formed, which should come out with an acid
--------------
on failure to remove the deposit, the last resort is the laundry with gravel or sand
