IIRC it's because of the environmental laws in the books. HCl is harder to
dispose of "legally" than citric acid is.

To add to the "stupid government regulations list", we use evaporative
coolers (essentially giant car radiators) at work. We buy potable water
from the city to spray down the outside of the coolers in hot weather for
improved cooling. We are no longer able to allow the water run off into the
back forty as it is now "industrial waste". We can drink it, but can't pour
it out on the back lawn to keep it green in the summer.
I am still waiting to see if the bright ass from the ministry realizes if
this is no different from when it rains on the coolers and will force us to
collect and "dispose" of the water properly...
