A dirty toilet can be a real headache. But according to Informe Brasil, lemons are a powerful weapon against limescale and unpleasant smells. Simply squeeze four lemons, adding the zest or juice to a blender with ½ liter of water. Blend the mixture and strain it through a sieve. Next, sprinkle baking soda around the toilet, focusing on areas with limescale stains. Then, pour the lemon mixture over the baking soda and let it sit for a few minutes. Scrub the toilet thoroughly. Finally, rinse and flush. The result? A sparkling clean toilet with a fresh scent.
