what is difference between ammonia and bleach??

I use ammonia when I want to do cleaning that involves cutting heavy duty grease and dirt. (Usually vinegar is my first choice.) I really only use bleach when I want to disinfect something (toilet bowl) or kill mold and mildew (shower area). Of course I occasionally use bleach in the laundry to whiten.

The real scientists here can give you a real answer; but basically chlorine-based bleach is not a soil-removing substance. As a detergent, its practically useless. However, in the absence of organic matter, its a cheap and effect disinfectant. In terms of "cleaning", its forte is that chlorine, being a strong oxidizer, is great for removing most stains.

Household ammonia is not magical, but you can add it to detergent solutions to raise the pH; and that makes it more aggressive against dirt and grease.

That's the basics, as I understand them.
