I bought the all natural mould remover and wall cleaner for my bathroom and also for my window sills. The mould was all,over my walls and ceiling and nothing would bring it off. I didn't want to ruin the paint on the surfaces and the previous scrubbing was starting to do damage, as a renter this was particularly concerning. I tried this as a last resort and didn't actually expect it to work at all. I sprayed it on and left it for a couple of minutes then wiped it off with a clean mop,for the walls and ceiling and a clean cloth for the window sills. It amazingly came away with no scrubbing at all. It just wiped off. I still can't believe it actually worked. It's just an incredible product.
