Toilet limescale can be a stubborn problem, but a cleaning expert has revealed that citric acid is a better solution than bleach or vinegar.
Why citric acid works
Sophie, the mind behind Sustainably Lazy, explained that the natural acid found in lemons dissolves the alkaline minerals in limescale, causing it to break down quickly. Unlike bleach, which is ineffective against limescale and can damage the bowl, citric acid is both effective and eco-friendly.
Sophie said: "The trick to removing limescale is with acid and heat. Commercial cleaners tend to use hazardous substances such as hydrochloric acid or sulphamidic acid, which are toxic to aquatic life and unpleasant to inhale."
She added: "They are definitely not the sort of chemicals I want in my home now that I have children. The acid of my choice is citric acid."
How to clean with citric acid
Sophie recommends cleaning the toilet in the evening, allowing the solution to work overnight. Start by heating water in a kettle, but stop just before boiling, and carefully pour it into the toilet bowl. Then add half a box of citric acid and leave it overnight. In the morning, a swift scrub with a toilet brush should remove any remaining marks.
For persistent limescale, the process may need to be repeated for another night. To prevent buildup, Sophie suggests keeping a box of citric acid near the toilet and adding a spoonful each night before bed.
Sophie said: "Alternatively, you could use white vinegar, but I find citric acid is more effective and works out cheaper and better."
