shelf life on ammonia for cycling?

[pugmom]

ok, my wonderful husband showed me a bottle of ammonia (no surfactants) from the depths of the garage. Given that it is a grocery store brand from a store that closed 6 years ago, it is at least that old.

Still ok to use? my guess is worst case, the concentration may be a bit off from what is labelled, but otherwise ok?

Test it. Put a little in with water.

Shelf life on a bottle of ammonia is reported tone anywhere from 1-3yrs

Sorry, my cell cut me off again! After this point, the concentration drops. Testing it is a good idea- put a drop in test tube.of water & see if you get a detectable ammonia level.
