\nI begin about Spray Nine in my post from November 18, 2025.<\/a> While it can’t be used for everything, it’s generally very good for non-painted, hard, non-porous surfaces.<\/p>\n \nSpray Nine has some ingredients quite similar, if not the same, as found on some disinfecting wipes – alkyl dimethyl benzyl ammonium chloride, or ADBAC (see my post from Dec 31, 2025 about ADBAC<\/a>). A cleaning cloth with Spray Nine added can therefore be used to disinfect surfaces in some similar contexts.<\/p>\n \nYet, Spray Nine also contains sodium hydroxide, which brings its pH up to around 12.7. Such makes it a good degreaser.<\/p>\n \nIn my experience, Spray Nine doesn’t emit fumes, just a low-key scent, so it’s pleasant enough to work with. I’ve used it for cleaning a bathtub\/shower stall, as well as to clean car parts.<\/p>\n \nThat said, Spray Nine can’t be used on glass, so one has to be mindful. Moreover, I believe I’ve seen it remove paint, so it’s likely not to be used on something with a nice finish. I think the instructions suggest to try it on an inconspicuous spot first to see what happens, before using it on area people will notice. For added caution, one might not spray it on a surface, but into a cloth, then wipe with the cloth.\n<\/p>\n \nWith gloves and eye protection, I’m satisfied that Spray Nine is pretty safe to use.<\/p>\n \nSource:<\/p>\n spraynine.com: safety data sheet<\/a><\/p>\n spraynine.com: technical data sheet<\/a><\/p>\n epa.gov: Spray Nine: EPA report<\/a><\/p>\nJack of Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.\n\n","protected":false},"excerpt":{"rendered":" Self-tutoring about cleaning products and some chemistry behind them: the tutor continues about Spray Nine.
