I've never heard of dipping clones in bleach.. I really don't think that would help the plants.. Rather I think it would destroy them. That shit is corrosive to humans, imagine what it will do to a cutting. Cloning is very basic, you just need to make the cut, dip it in cloning/rooting gel or powder, and into whatever medium you use. It is important, however, to keep the conditions ideal at that phase, as if they are too inadequate they probably won't root. (happened to me on my first cloning attempt.)
Please don't try to cut the clones under water and definitely don't dip them in bleach..
And good luck
