Cillit Bang Black Mould Remover Spray I Removes Mould, Mildew & Dirt I Size: 750ml (Pack of 1)

I had been battling stubborn black mould on my bathroom silicone sealant and grout for months, scrubbing with bleach and other cleaners with barely any results. Then I tried Cillit Bang Black Mould Remover, and wow – it actually works like a miracle. You simply spray it on, leave it for about 10–15 minutes, and come back to see the mould literally disappearing before your eyes. No scrubbing needed. Just a quick rinse or wipe, and the surface looks sparkling clean and white again. I couldn't believe how effortless it was. The spray nozzle creates a thick, clingy foam that stays in place even on vertical tiles and walls, so it really gets to work without dripping off. Yes, the chlorine smell is strong, so you'll want good ventilation and maybe gloves – but that's exactly what gives it its power. For tough jobs like shower corners, window seals, and behind sinks, nothing else I've tried comes close. It's now a permanent fixture under my bathroom sink. If you want a fast, effective, no-scrub solution to black mould, this is the one. Highly recommended for restoring your bathroom to a clean, healthy state!

I cannot recommend this mould treatment product highly enough – it has exceeded every single one of my expectations and is by far the best product I’ve ever purchased for tackling mould. I had stubborn patches in my bedroom and around a window frame that I had tried multiple other solutions on with little to no success. After following the simple application instructions, the mould started to disappear within minutes, and even earlier than the recommended time frame, every trace was completely gone. The surface looks clean, fresh, and like the mould was never there at all. The ease of use and incredible effectiveness have left me more than satisfied – it’s saved me both time and money that I would have spent on professional treatments or inferior products. If you’re dealing with mould issues, this is the only product you’ll ever need to buy. I have attached the photos before and immediately after application.

Spray a black moldy ceiling. Stand back and watch the magic work... cover clothes and hair and weather a mask. Beautiful white ceiling again. Works everyone. No need to paint!

Reasonably strong and effective. Not so great on ALL black mould. Elbow grease required. Effective spray. Bleach smell.

Works well and does the job.

This stuff is amazing. Mould on grout in shower cubicle. I sprayed it on, left it for 15 mins as specified and when I came back the mould had gone. Even with the product running down the wall! In addition the discoloured yellow mastic was bright white again! I thought I’d have to scrub the mould and thought this would be the first trial but have nothing to do! It’s gone. I’m amazed, shocked, stunned. It does what it says, which for black mould removers is impressive! You won’t beat this product! Fantastic.

Does the job n gets mould off easily

This is nothing special, and certainly not ‘No 1’. Irritatingly, the poorly designed sprayer stops working when there is still plenty of fluid left in the bottle. Go for something else.
