I use bleach for cleaning glass bottles, but not my plastic fermenter, following Palmer's advice that plastics pick uo a lingering chlorine scent after successive uses. I do not find bleach hard to rinse, but the water here is very soft, almost devoid of calcium and magnesium. Where you have hard water, bleach might precipitate sulfates and carbonates and cause that stickiness one commenter referred to.
If you follow bleach with an acid sterilizer such as Starsan or Defender, be sure to rinse the bleach. Acids release the poison gas chlorine from chlorine bleach, and the two products would neutralise each other more or less, depending on thye concentrations of each proiduct.
Is there any source in Australia for buying pure sodium percarbonate, without the detergents in Napisan, etc.?
