Really good cleaning power clears moss and all that green mouldy stuff that is hard to get off with normal cleaning methods. Spray functioning is perfect and so fast it really shifts anything in its path. Such good quality and value for money. ### ⭐⭐⭐⭐ Good prduct. *by G***. on 22 April 2025* The actual solution worked really well clearing the green mould on my fence within a few days. The only thing i would criticise is the free spray gun adaptor. It wasn’t really up to the job so I used a spray bottle I already had to apply it. All in all a good product at a cheap price. I would buy again in future. ### ⭐⭐⭐⭐⭐ Easy to use, pleased with results *by V***S on 24 April 2023* I purchased this to clean up my old decking which was more or less green all over. I did not have high expectations as my decking is now old and I didn't treat it last year.As soon as the solution dried I could see a difference and 24 hours later the decking looked the cleanest it has in years and is now ready for staining.Unfortunately I forgot to take a picture before the cleaning treatment.I really liked that it was ready to use.The only slight negative would be the trigger hose it isn't great, but does work.I have only tried on decking but have plenty left to use on my path and front paved garden. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/511928205-2-x-5-litre-ready-to-use-spray-and-leave](https://www.desertcart.gr/products/511928205-2-x-5-litre-ready-to-use-spray-and-leave) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
