When you think about it, stuff that powerful is
bound to cause some sort of deteriorations! All disinfection chemicals (even the bleach under the kitchen sink) needs to be used with care. To me, that's the real issue right there ... the "quality" of CSD (insert whichever acronym you prefer) staff themselves! I well remember a guy who never bothered to close the main water valve every evening ... then went off on holiday ... a plastic connector, under pressure, "popped-off" ... and no-one phoned us until there was water running into the elevator shaft (and still none of the staff had the
nous to simply wade in there and close the stop-valve)! What a mess!
