Fantastic! I wish we had discovered this spray long ago as it would have saved so much money wasted on other products. It does what it says! Spray it on, leave it for a while and the black stains will have been removed as if by magic! We've used it on pvc windows, on grout, on silicon around the sink. It really does work! The only place I know it is sold is B & Q but it is definitely worth a trip to get it and worth every penny!

In my bathroom, I have long been plagued by black spots of mould and mildew constantly re-appearing on the tile grout. No matter what I tried, it never completely went and came back all too soon. I have, more than once, raked out the joints and replaced with anti-bacterial and anti-mould grout, to little and temporary avail. And so I tried this stuff. Only cost around a fiver, so no great loss if it didn't work. Took about 5 minutes to apply, left it for 30 minutes, then rinsed off, and WOW- all the grot was gone (and hasn't made a reappearance as yet). Some users have complained of the pump packing up, hasn't happened to me. All I would add is that this stuff is contains a VERY strong bleach, make sure you don't breathe it in. Brilliant product.
