I was told not to bother her in another thread, to do searches, which I have been. To me, a guy who has to know everything, so I can forget it later, there has to be a definitive answer. This article - What Is Bleach and How Does It Work? leads me to believe that the life is 6 months. They even state that clorox bumps it up (sh) because they know it is going to start breaking down during shipping, especially during summer heat. I read a scientific piece where they put the date at 166 days (effective). Most of the studies I have read are being done by people in the medical field, more specifically, dentists. Once again, relating this to pressure washing, if time lessens it’s ability to kill algae/mold/mildew I would want to know that. I would be a small time operator, so storage would be an issue.
40% Sodium Hypochlorite - #34 by CaCO3Girl this is what she said in an earlier thread if I linked it right
I have to edit this again, here is the gist of my question: If 6% (more or less) is only effective for 6 months, and higher strength/concentrations break down quicker, at what point does 12.5 or 10% become ineffective for removing algae/mold/mildew. I won’t throw in the variables of higher temperatures, although that is likely to be the case.
Think i’m done wrapping my head around this. Gotta get up early for the vets day parade.
