It might mean applying it a few times before all it goes. I did this at different times of the day. **Q: Can I use this on a bedroom wall,would it work?** A: I looked at the instructions on the actual bottle. It says it will damage the paint and many metals as well as enamel. I would not use it on any painted surface or anything that is not hard, like bathroom tile. Hope this helps. We use it in our shower and sometimes in the toilet and it works great there. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by O***E on 22 May 2026* Amazing product, it works in minutes and the mould hasn't come back. I would recommend 100%. ### ⭐⭐⭐⭐⭐ Good product! *by O***N on 27 April 2026* Good for cleaning moulds ### ⭐⭐⭐⭐ Effective easy to use product if used correctly *by N***7 on 17 December 2025* Used this product before. It is very effective and reasonably easy to use on larger areas although some care is needed when spraying wall tiles. Can cause some streaking if not removed reasonably quickly. Not easy to apply in very small areas or edges of tiles which have been laid to form a pattern and protrude slightly. This product is strong enough to do a perfect job even if removed within a very short time span. It is quite a potent smell so would suggest windows are opened if possible as could possibly affect people with asthma or chest conditions. Having said that my experience is that this product works quite speedily if any mould areas are kept regularly under control. I would recommend ensuring you read any instructions on any of this type of product in order to use correctly and gain maxim effectiveness and irradication. ## Frequently Bought Together - Astonish Specialist Extra Strength Mould & Mildew Stain Blaster Spray, for Fast Mould Removal, 750ml - Astonish Specialist Limescale Remover, for Dissolving Limescale and Rust, Spray and Dissolve without Scrubbing, Lime Blast, 750ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/477241095-specialist-extra-strength-mould-and-mildew-stain-blaster-spray-750ml](https://www.desertcart.us/products/477241095-specialist-extra-strength-mould-and-mildew-stain-blaster-spray-750ml) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-11*
