if anyone knows where to get quaternary ammonia, the sanitiser used in commercial institutions, please PM me with the supplier.
as for cleaning:
rinse off solid materials with hot water.
wash with soapy solution.
rinse
sanitize with sanitizer. chlorox is good but it oxidizes soft metals (pretty much all but stainless steel). you can use like 50ppm or something and let it air dry. yeah, sunlight and wind really helps. Quat rocks as it doesn't vaporize, but stays down and sanitizes. there are enzyme cleaners/sanitizers that actually eat biofilms where microbes are said to grow. doubt you need to worry about biofilms but i don't know.
restaurants use a three system sink. Wash with hot soapy water; rinse with hot water and then rinse with sanitizing solution. let air dry.
i've heard dishes at dorms were said to have much higher bacterial numbers when they didn't go through a heat dry cycle. but only heard about this odd study. but it makes sense to sanitize and take away any harbouring environments to keep the bacteria from protecting themselves for dormancy. kill them while they're growing.
again, if anyone knows where to get over-the-counter Quat, please PM me.
