Works good, very strong, the only thing when I went to use it again, the spray adapter was blocked and I run hot water over it but it didn’t spray. I called smart seal and they sent out a replacement immediately so very happy with the Custer service. Highly recommend

Wonderful!
Works a treat
Does what it says. But does have a strong bleach odour.
Has worked very well on stubborn satins in tile grout.
Mould is never easy to clean but I think that this product was effective.
This is a very effective product and the results were better than what I thought.
I've used other gel style mould removers before that worked, but were a bit of a palaver to use. This is a simple spray, that just works! I left it on overnight and the difference on the show sealant and grout is startling - back to white and clear of the discolouration and mould that had been there before. I'm interested to know how long the effect will last, but just for how quick and well this works, I'm imressed.
Great product, worked really well
Used this to clean the travertine tiles in my shower cubicle. Worked very well and removed black spots and stains, just a couple of stubborn stains that needed a second application. Happy with the result :-)
just followed the instructions on the container, had to reapply on stubborn patches on silicone sealant and left it for an hour or so and it removed all the mould and left the marble tiling untouched.
Brilliant product! Bought to remove mould/mildew from my mother’s white marbled headstone. In my experience, it couldn’t have been easier... sprayed on, left for around 25-30 mins and only needed to rinse off, with fantastic results. A job very well done, where other products have been less effective. Will be purchasing this again and would definitely recommend.
Does what it says on the bottle!
Took a bit of elbow grease as well. But got rid of most of the mould on the tiles. Better than any product I have used for mould before.
