If my experience is any guide, it is probably a bad gauge.

It won't do too much damage if it is diluted by rain or the hose, but I 
would avoid any concentrated amount.

For unloading, I just remove the valve and let it run out. But, unless 
you remove the tube and squeeze it, you will still have some sloshing 
around in there forever. When I encountered unwanted calcium and leaking 
valves in the past, I just "bit the bullet" and bought a new tube. 
Probably over kill, but see

for an image of what leaking calcium chloride ballast can do to a rim 
over time.
