D.M. Procida wibbled:

The grout on the new shower is already showing signs of black mould
spores. Since we have a chance to nip this in the bud, what would be the
best way of doing so?

Thanks,

Daniele

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?

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

Cheers
