Not very effectice

Not great at all, once you wipe it just spreads the mould.

Effective and speedy

Bought this to get rid of a huge mould patch on a ceiling that had been there, apparently, for a couple of years. Needed to sell the house and this got rid of the mould pretty quickly and effectively. Painted over with Ronseal mould cover Matt emulsion and it looked as good as new.

quality product

I bought this product as I was looking for something of better quality that could reliably remove mould, having wasted money in the past. I was not disappointed. I used this product in various places around the house, including ceilings and walls, and in the bathroom. It removed mould easily and effectively, and I was pleased with the lack of scent (compared to other products for mould removal.) Some areas needed a 2nd application. Overall, I recommend this product as it works and does not leave a horrible smell!

Did the job well

Does exactly what it says on the tin and was easy to use.
