Smartseal Rayleigh Review by David W, 2026-05-15T16:34:29
Brilliant stuff. Cleaner is easy to apply, works quickly and is very effective on roof tiles with near instant results. I'd recommend it to anyone. The only time I've needed a second application is on an area I missed the first time. The product is good value (especially when buying 3x5 litre) and arrived quickly. Possible tip to users: if your roof is full of moss, look to scrape as much off as you can before applying the roof cleaner. Otherwise the moss will turn a dirty white colour, but will still be attached.
