Can you still get 'oxygen bleach', and where from?
(This is a substance based on hydrogen peroxide, as opposed to the usual sodium hypochlorite).
I've not seen it in the shops for a year or two, and a local janitorial supplier hasn't heard of it, although bleach tends not to be used for commercial cleaning IME.
I need it for cleaning my flat (actually a Housing Association bedsit with shared laundry and bathroom), I don't use the normal stuff at home because if it gets onto clothes it damages them, but for a lot of cleaning jobs you can't beat bleach. I recently cured a bad smell in a cleaning cupboard at work, by getting some bleach from the nearby supermarket and putting it down the sink. Got all the stains out of the porcelain too, which the approved chemicals wouldn't shift.
