Personally I wouldn't worry too much about it UNLESS you are allergic to th=
e
mould. It's improving the plasticity of your clay, and otherwise not doing =
a
lot of harm.
Unsightly maybe, but other than that merely a visible manifestation of what
surounds us on a daily basis.
In my workshop I have a small bottle of concentrated disinfectant which I
occasionally add to my wash-up bucket when it gets too "ripe". Mostly I add
the "ripe" water to my reclaim to assist its "developement"!
I throw with slip as opposed to water, and have to add that to the reclaim
pretty often as that is also prone to going off as well.

Hi Brigit,
If you do only do a little - I got some in clay once and it foamed -
was unworkable - when it dried it was full of holes.

Dear Birgit Wright,
Hydrogen peroxide available for public sale is a dilute solution of this
compound and Water. In this condition it is neutral to indicators so would
not be expected to alter the nature of plastic clay or deflocculated clay
slip.
It is used in the art world to clean darkened paintings.
A weak solution of Copper sulphate (Blue Vitriol) might be a better
Fungicide. Have a look through Clayart archives for previous discussions on
the topic of Mould.
