Kilrock Mould Remover Brush-On Gel 2 x 250ml - Eliminates Mould & Mildew - Accurately Target Areas of Mould Growth - For use in Baths, Showers, Corners, Edges, Grout Lines

Used to be able to get this in my local shop but no longer stocking it so Amazon to the rescue. Great product, sticks to surfaces and easy to apply with the brush. Brilliant on the washing machine door seal☺️

This thing is witchcraft, plain and simple, no one can tell me otherwise, it took just about 4h for the black stain on the silicone sealant around the bathtub to magically vanish. You could watch it work in real time, just. Never before have I seen a product, bleach or otherwise, clear those black stains from the silicone.

Works well transforming clear silicon that has turned black

Item is excellent, unfortunately the packaging was insufficient and the item had leaked inside the packaging. Really needs to be boxed properly.

Very good does what it says

I have tried other products, but this one did remove the black mould and stain in silicone. It did take two applications, but it worked.

I saw reviews of the product being spilt but decided to take the risk. My bottles were also spilt. It’s a safety hazard as I accidentally touched the leaked bottle and got the chemical on my hands. Even after washing the bottles and putting the lids on tight, one of them is still leaking somehow. I’m going to have to tape it up if I want to use it. UPDATE: I tried using my taped-up bottle and it had ZERO impact on the mould in my shower despite using a generous amount of product & leaving overnight. I washed it all off and used a normal anti-mould spray which worked.

This is the best stuff for cleaning black silicone
