    Fast working, excellent for stubborn staines

    Was very surprised on the power from this little bottle. It will stain your clothes very badly with bleach but that’s expected and results are well worth it!

    Great Mould Remover - Highly Recommend

    I bought this Kilrodk brush on gel and the Kilrock Mould Remover spray together last week as I had some mould in my bathroom which has been difficult to remove. I've tried lots of other cleaners, but nothing has been able to remove the mould, so I bought these 2 Kilrock cleaners after reading some good reviews about them - but had my reservations. I used the brush on gel first to work on some mould spots on the grout between some of our mosaic tiles and found that it worked really well. There were some faint black marks still when I rinsed off the gel but I think I could see them because I knew where they were. The following day I used the spray on all of the bathroom tiles, left the spray to work for around half an hour and was amazed at the difference. The bathroom tiles looked sparkling, and I can't see where the black mould spots were now. There was an added bonus of the removal of some orange limescale in the corner of the bathroom too. I'm so pleased with these products that I will be recommending them to people. Follow the instructions for use carefully, maybe use some decorators goggles to protect your eyes and use a dust mask to stop you breathing in the fumes - make sure the room is well ventilated too. The product smell does hang around for a few days too, so bear that in mind when using the products.

    Kilrock Blast Away Mould Remover Brush-On Gel

    I've bought the mould remover to clean my bathroom tiles as they looked quite moldy due to humidity. I was in doubt if the product would work, but following the easy instructions, I've applied it to the tiles and after 1 hour they were pure white and shiny. I do love and recommend this product as after applying a simple layer I could see the results in a blink of an eye! Thank you Robert Dyas for selling such an amazing product!

    Does Not Work

    I bought this product after being very happy with the same make descaler, now wish I had not bothered. I needed it to try and rid a couple of small patches of mould in the bath silicon seal. Despite several attempts the mould had not even lightened in colour let alone disappeared. Removed easily with Muffycid in the end
