I do have some Jacquard Discharge Paste, but having tried it once again recently, I have decided I just cannot stand the smell. It is one for the rubbish bin. I don't like the smell of bleach either but it is far less unpleasant.
By the way, and I am sure that as sensible people I don't have to warn you not to try this, but I did; I tried discharge paste on a sketchbook page, completely forgetting that I had previously stuck in an encaustic image -- ironing the page, as you can well imagine, made a terrible mess of the wax on the previous page. Funny in retrospect.
