Hmm, that's very bad.

I have some 7.5% ammonia, and that is seriously bad smelling.

You see, we don't use "household ammonia" here usually, just as we don't  
use bleach, or IPA as rubbing alcohol for that matter.

Substitute products are rarely in pure form, and usually sold here as a  
brand product with unknown composition.

Google says "Household ammonia is a dilute mixture of 5 to 10 percent  
ammonia gas in water", i will search around some more.
If you had a brand for the ammonia i could probably spy the percentage  
 from the msds.
