    Simply no mould

    Unfortunately the product failed to work on grout mould but might with other applications. ** Hi Wendy, it will definitely have killed the mould, however Simply No Mould has a mild 'bleaching' (whitening) action, so if the mould is bad it will need another application to whiten further. A white scourer for stubborn mould is very helpful. You can read about this on the label. Further applications can be done over a few days, so no need to spend time in one go. All the best, Becky

    Was not expecting this product to be as effective as it is. When used correctly, it removes mould without any smelly residue. Spray then rub over the mould to remove.

    Simply amazing!

    This has changed shower cleaning forever! Just spray it on the wall and floor tiles, leave for several hours, and scrub the grout with a small brush. Everything comes off, and there’s no toxic smell. It doesn’t even need rinsing as it goes on working for ages. Just a brilliant solution.

    This product is effective in reducing mould in the shower

    Published by Linda McMullen on 26th Nov 2022

    I keep a bottle by the shower. Recently I went to reorder and found the only bulk-size bottle was 5 litres - which is way too big and heavy to be refilling a 500 ml spray bottle. I'd like to see a 1.5 or 2-litre size available.

    No Mould

    Published by Anne Stone on 22nd Dec 2021

    Works quite well, but sold on the fact it isn't harsh on the tiles and the fact it doesn't take my breath away. I will just scrub a little harder! SimplyClean Response Try using a white pool scrubber ($2 from the supermarket) to get into the grout lines. Best wishes, Becky
