Best cleaner to clean bathroom grout

[Longshanks]

Hi

Have v bad grout stains in bathroom. Only way I could previously clean was with indoor spray thing. Problem with that was it eventually eroded grout.

Be grateful if pros could suggest best cleaner in these circumstances.

Thanks

bleach...... water it down so you can spray it through an old bottle ..spray it on and leave it for as long as you can.

Agreed, good old-fashioned bleach.

Mould build up is due to poor ventilation.
