The grout on the new shower is already showing signs of black mould

best way of doing so?

Thanks,

Bleach first - get it killed - it's not permanant - if mould likes your
shower, the spores are always going to be floating around - but I've
found
bleach keeps it knocked back.

Is it the grout or silicone or something else that's sprouting the mould?

Grout won't grow mold, but it might have soap scum on it which is.
An old washing-up (or similar) brush will remove the soap scum.
(Probably easiest to do this whilst actually having a shower;-)
Use of liquid soap will stop the soap scum (although liquid soap
itself goes moldy, but hopefully it will wash off before that happens,
unlike the soap scum.) Alternatively, try one of the daily shower
sprays, which is a weak surfacant (detergent) and sometimes weak acid,
to help make the scum run off and/or dissolve before becoming encrusted.

Silicone will grow mold. You can buy it with anti fungal, but that
will get washed out of the surface after a while.

Bleach is good for making dirt invisible and will knock out living
things whilst it's in contact, but it's not a cleaner, so any effect
is going to be short lived as it hasn't changed the reason for the
mold, and long term it might damage other things.

Are you a bit down on ventilation - places that can dry out periodically
are
less attractive to black mould.

Best think I ever did was to stop using bar soap and to use only liquid
soap. Everything stays sparkling and shiny( Except me)
