A product that lives up to its title Wet & Forget and also does exactly what it says on the tin!”
A friend told me about your product several years ago and I’ve been used it ever since. I’ve also recommended it to so many people, they must think I’m on a commission!
Q. Why have you swapped the 5L bottle for 4L? Less expensive but I’d prefer to pay more and have the extra volume.
Thank you so much for your wonderful review! We're delighted to hear you love our product and appreciate your loyalty. Regarding your question about the 4L and 5L bottles, I'm delighted to say the 5L bottles are now back in stock and available to order! Thanks again for recommending us and for your support!

I was recommended this product by my brother-in-law. I haven’t quite seen the results he had but maybe I’m being inpatient and there hasn’t been much rain to activate the product on my stone patio slabs.
It is slowly beginning to look brighter but it has been some weeks.
Product however is very easy to apply

Was informed of this product by a friend. Have used on my Indian paving which would normally power wash. Have sprayed on Wet and Go and the difference is quite outstanding. Have now sprayed my paving on the drive and would recommend this product for ease of use and final display. Each time it rains it gets better and better.
