Also never seal oxygen bleach solution in water(e.g powdered oxyclean dissolved in water- not a store bought LIQUID bleach) in any kind of jar, it produces enough oxygen to be somewhat hazardous- if its concentrated solution it can be used as an oxy generator. Magenese dioxide in H202(peroxide) does the same a little faster.
There are quite a few things that should never come in contact... ammonia and bleach, acids and bleach, ammonia and alumnium.... the list goes on..
