Bathrooms often become breeding grounds for mould due to damp conditions, particularly in grout and corners. Cleaning expert Chantel Mila, known as Mama Mila, has shared a powerful four-ingredient paste to combat this issue. The mixture consists of 1 cup of baking soda, 0.5 cup of hydrogen peroxide, 1 tablespoon of washing up liquid, and optional tea tree oil. This paste effectively eliminates mould and shower scum while preventing future growth. Baking soda alters the pH, creating an alkaline environment that hinders mould proliferation. Hydrogen peroxide functions as an oxidizing and bleaching agent, restoring grout to its original whiteness. Tea tree oil, known for its antifungal properties, enhances the mixture's effectiveness against mould spores. Mila recommends applying the paste to grout with a squeezy bottle, letting it sit, scrubbing with a sponge, and rinsing thoroughly. Experts confirm that tea tree oil is particularly effective against common mould strains and provides a pleasant scent, making the cleaning process more enjoyable.
