"Just remember that once you open the bottle, any unused solution will have a limited shelf life." I have to agree with this. When I was sterilizing my magnolia cuttings, I noticed my clorox didn't smell or look greenish yellow so I bought new. (Long ago, I made the choice between functional elastic or bright white underwear so my Clorox had been around for a while). Check it out before you use it. The laundry use is purely a learned obsession but cutting sterilization is a must. I wondered if they put detergent in the Clorox because it felt soapy but I realized it would be saponifying the triglycerides in my skin because the NaClO would be as caustic as NaOH since hypochlorous acid is so weak. I suspect the outer cells of nearly everything are destroyed by NaClO but us multicellular organisms are usually clad with disposable protective cells On Thu, Sep 7, 2023 at 1:34 PM Robert Lauf via pbs < pbs@lists.pacificbulbsociety.net> wrote: > If I were going to sterilize cuttings, I'd go with diluted clorox, but > for more sensitive things, esp. embryo rescue, dipping them in hydrogen > peroxide is usually sufficient to avoid contaminating the agar with mold > while not killing the embryo.
