I try not to spill the solution everywhere but do get some  on the bark . I haven't noticed much bark necrosis from the spillage. On the other hand-continued bark die back has occurred where the oxidizing agent (bleach) wasn't used or where the bark was not excised back to live tissue or VERY near to live tissue. You will note that my solution is considerably weaker than the 10% sometimes suggested. I suspect that it is still far stronger than needed. JPS had some info on bleach as a sanitizer a couple of years ago.-Bottom line was that the solution can be quite weak if it is allowed time to work. I've been hesitant to drop the chlorine percentage further simply because what I've been doing has worked.
