It can also be used on tile grout and is also amazingly effective on a rubber washing machine seal (gasket). This stuff seems to keep acting even after initial application. **Q: Can I use this on a rug?** A: It depends on what you are trying to get rid of - this is a green algae killer and is designed to soak into wood. I wouldn’t give the woollen fibres of a carpet much hope of standing up to this chemical. Try something designed for wool **Q: I have rust all down a section of my monocuse render. Would this remove it?** A: Sadly, no **Q: Can this be used on fibreglass roof?** A: Hi there. The product info on the container say it can be used on most plastics so I'd say it would work on fibreglass. It is potentially harmful though so if I were using it on a roof I'd want to avoid it going into the gutters and then into the drainage system. I've used it on pebbledash walls and a wooden fence to good effect. On pebbledash I needed to use a stiff brush and water after applying it to get the full effect but on wood I just left it and it killed off the moss. On fibreglass I'd imagine it would need a bit of stiff brushing too - but maybe not. Easy to apply with a pump spray-gun too. ## Frequently Bought Together - Everbuild 404 Fast Powerful Fungicidal Wash – Removes Lichens, Fungi and Algae – Exterior and Interior use – 5 Litre - Charles Bentley Stiff Bassine Wooden Hand Scrub Brush, 8", Wood, Natural, One Size - Everbuild 401 High Strength Brick and Patio Cleaner, 5 Litre --- ## 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/55486946-everbuild-404-fast-powerful-fungicidal-wash-removes-lichens-fungi-algae](https://www.desertcart.jp/products/55486946-everbuild-404-fast-powerful-fungicidal-wash-removes-lichens-fungi-algae) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-13*
