Behind our kitchen sink some black mould has grown along the join with the Work top and wall.
There's also a wee bit in the grouting on the bath which is black and a weird orange colour. It just keeps returning.
Afaik black mould can be toxic so does anyone know any safe ways I can clean it up? Ideally with some preventative measures so it doesn't keep returning. I've tried all the usual cleaners including bleach.
Thanks
