Bye bye mold 👋
Got rid of the mold on my window fill in an instant, definitely would recommend, but use as instructed and not like me where I thought it wasn’t working and sprayed wayy to much and there was a stench of chlorine for ages but went a way after a short while. It’s definitely very powerful and I have had no leakages so far so would recommend for getting rid of your mould 👍🏻

Working so far
This has worked really well in my bathroom shower, it has taken most of the mould off, just have to wait and see if continues to keep my shower mold free

Great for shower curtains
This is the first product that has truly worked on my disgusting fabric shower curtain. The curtain had loads of mould and soap residue on it, so I took it down, placed it in the bath and sprayed a copious amount of the product onto the problem areas. I let it sit for an hour and then rinsed and repeated. I then put it in the washing machine on a cool wash. The curtain has come out so well, I wish I'd taken a before and after shot. I would definitely recommend it for shower curtains. The only problem is that the product smells very strong, so make sure you use it in a well ventilated room. I had all the windows open and had two air purifiers running whilst I was using it. I wouldn't recommend using it if you are sensitive to chemicals, or if you have small children or pets, as I think it is incredibly toxic

Best mould remover I’ve used
By far the best mould remover I’ve ever used. Used on garden sofa where all the fabric mesh had got black mould over it. Tried a more formal fabric spray (expensive) which did nothing. Ended up using it on the inner cushions and outer cushion covers (washed after to remove any product), worked perfectly.
