Astonish Mould and Mildew Blaster It just melts the black mould away. If it's really bad, use it twice. Nothing in my opinion work better. No toothbrush scrubbing needed. it's amazing only costs only £1 in Wilkinsons or bargain shops
Beware of using Cillit Bang in an enclosed space. I tried using it in the shower cubicle ( on the grout not me ) but couldn't breathe, I had to open the window and get some fresh air. I do have asthma although not seriously, never used this product since.
Having tried all sorts in the past, I now use Cillit Bang black mould remover.....it works! Just spray on and leave for an hour then use an old toothbrush or small sponge on the area. Repeat if necessary.I even used this product on the base of the hall curtains when they showed a bit of mould once, all traces just vanished.
I second what Oopsadaisy does. I do it once a month and it keeps everything in the shower clean including the chrome edges of the glass door. I also use it around the bases of taps and the plug holes in the hand basins and bath. Mould spray also works but this is cheaper.
Loopyloo you need to re grout. As the black mould will keep coming back. Also water could be getting behind the tiles. All the old grouting needs to come out before re grouting. As no point in putting new grout on top of old. It's a messy job. But worth it.
I just spray with Dettol (or similar) mould spray and leave it overnight and then rinse off in the morning. Easy and does the job. I sometimes repeat it for a second night if all the mould hasn't gone first time.
I always use neat bleach on an old toothbrush on tile grouting, but if your grouting has fallen out then you will need to take all of the old grouting out and regrout. My DD has a hand held steamer that she uses on tile grouting, gets it super clean.
Can anyone recommend best way of cleaning black mold off bathroom tiles. Also we have little mosaic ones and the grouting has gone. What's the best product? Many thanks.
