A soft brush can be used to remove organic growth on badly contaminated areas. **Q: How would your product be applied to a house roof?** A: Green Clear PRO is usually applied by a sprayer. In the case of house roofs, depending on access, it can be sprayed from a ladder or scaffolding. If the roof is not that high, then it can be applied using a sprayer and an extendable lance. **Q: Does it also clear weeds, please?** A: Green Clear may kill some types of weeds, but is not regarded as a weed killer. It would be best to purchase a specific weed killer for that purpose. **Q: Is this product animal/bird friendly?** A: We would not classify the Green Clear Pro as animal or bird-friendly immediately after application. Once dry, it is totally safe for birds and other animals to walk on. **Q: Is the product acidic?** A: No, Green Clear is not acidic. ## Frequently Bought Together - SmartSeal Green Clear Pro - Powerful Green Algae Remover - Easy To Apply Best Mould, Lichen & Black Mould Remover - Perfect Roof Cleaner & Driveway Cleaner - (25 Litres) - Spear & Jackson 5LPAPS 5 Litre Pump Action Pressure Sprayer --- ## 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.jp/products/90561603-smartseal-green-clear-pro-25l-concentrated-biocide-and-green-growth](https://www.desertcart.jp/products/90561603-smartseal-green-clear-pro-25l-concentrated-biocide-and-green-growth) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-24*
