ZERO concern on use of bleach. I currently use it for white trim on house that gets mildew and have for 20 years. I mix it 1:1 with water, and it is excellent.

My need is to "clean" a rock walkway/patio/steps. I have never considered it for the rock seufaces since the issue is not really mildew.

Ever tried it?

Thanks...
