Just so us Europeans can get it right Peggie:

5-7% household bleach,

Correct. Plain ol' household bleach.

Look out for the labelling 'safe for potable water' or the warning
'not to be used in potable water systems'.

Nope...all household bleach will carry a warning that it's not for
consumption. If it were safe to drink the concentrations necessary to
kill the "critters," it wouldn't kill the critters.


Thanks to you and others for translating the impenetrable volume measures we
handed to the USA on independence! I do prefer the simple decimal system.
There's less for my aged brain to remember.

Yes, all bleaches are labelled 'not for consumption' - or should be.

In Europe it is now becoming harder to find 'plain old household bleach'.
Certainly, no brands call themselves that. Marketing pressures have created
a large number of other products (generically - thickened bleach) which have
added perfumes, scents, detergents etc etc. , and most still call themselves
'Household bleach'. Some are labelled 'unsafe for water purification', 'not
to be used with potable water systems', but not all are.

Some of the 'plain old household bleach' brands are labelled as 'safe to use
with potable water', 'safe to use in water systems'. In Greece these are
important products where the main source of water is the household cistern -
collecting rainwater and storing it for half a year. I think their biggest
use in UK is cleaning beer pumping pipes in pubs and washing out fish market
stalls!
