The whole conversation about the explosive character of ammonia is academic. Ammonia (NH3) can be explosive in certain high concentrations in air. The household or commercial ammonia from the store is NH3 dissolved in water and is actually no longer ammonia gas except in a low concentration and is not explosive. The problem with commercial grade ammonia is the high concentration which is corrosive and irritating to the lungs, skin, eyes, nose, etc.

And yes, the low concentration household ammonia will work for fuming if you give it sufficient time. The issue is one of concentration of the gas over the piece in question.
