Many others, however, recommended using bleach.
Ali Molloy said: “I pour bleach on all the horizontal grout lines and leave it to soak for a few hours. It removes all the mould, without scrubbing.”
Kirsty Elizabeth commented: “Bleach soaked cotton pads, leave overnight. I did it a few days ago and the mould was completely gone when I took the pads up.
Lynda Mcculloch agreed: “I did mine the other night put bleach on it left overnight gone the next day xx”
