Mould in the house is more than just an eyesore; it poses significant health risks, especially for those with respiratory issues, allergies, or compromised immune systems. While using bleach might seem like a quick fix to eliminate mould, this common solution might worsen things. In a post, Ava Abrams, an Australian alternative healthcare promoter, warns against this practice. She says, “Never put bleach on mould. If you put bleach on the mould, you will create one of the most toxic mixtures on the planet (sic).” View this post on Instagram A post shared by Ava Abrams (@beautiful_holistic_) Dr Jagadish J, public health intellectual, tells indianexpress.com, “While bleach might seem like a quick fix, using it on mould can create a toxic environment and leave the root of the problem unaddressed.” What happens chemically when bleach is sprayed on mould? Dr Jagadish mentions, “When bleach, a solution of sodium hypochlorite, comes into contact with mold, a complex chemical reaction occurs. Bleach is primarily effective against bacteria and viruses, but mould is a fungus. While bleach can kill some surface mold, it fails to penetrate porous materials like wood and drywall, leaving the mold's roots intact to regrow.” Moreover, he states that mixing bleach with certain types of mold or even common household cleaning agents can generate toxic gases. For instance, combining bleach with ammonia, a compound sometimes released by mould, creates chloramine gas. This noxious gas can cause respiratory distress, chest pain, and irritation to the eyes, nose, and throat. Even mixing bleach with organic matter like the cellulose found in wood can release volatile organic compounds (VOCs), which can irritate the lungs and have long-term health implications. Potential health risks The potential health risks associated with using bleach on mould are numerous. According to Dr Jagadish, these are: Respiratory Issues: Inhaling bleach fumes or the toxic gases produced by its chemical reactions can irritate the lungs and respiratory system. This can be particularly dangerous for individuals with asthma or other respiratory conditions. Skin and Eye Irritation: Bleach is a corrosive substance that can cause skin burns and eye irritation upon contact. It's crucial to wear protective gear like gloves and goggles when handling bleach and to avoid splashing or spraying it near your face. Long-term Health Concerns: Prolonged exposure to bleach fumes and the byproducts of its reactions with mould has been associated with an increased risk of respiratory problems, neurological issues, and even certain types of cancer. Safer and more effective alternatives Thankfully, there are several safer and more effective alternatives to bleach for mold removal, says Dr Jagadish. These are: Vinegar: White vinegar's acidity can kill many types of mold. Mix equal parts water and vinegar and apply to the affected area. Allow it to sit for an hour before scrubbing and rinsing thoroughly. Baking Soda: Baking soda is a natural fungicide and deodoriser. Make a paste of baking soda and water and apply it to the mouldy area. Let it dry, then scrub and rinse. Hydrogen Peroxide: Hydrogen peroxide has antifungal and antibacterial properties. Dilute it with water and spray it on the mould. Let it sit for 10-15 minutes before scrubbing and rinsing. Tea Tree Oil: This essential oil has potent antifungal properties. Mix a few drops with water and spray it on the mould. No need to rinse. DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.
