Vinegar and Lemon
Both ingredients contain acids that dissolve toilet stains and limescale deposits, while also eliminating odor-causing microorganisms.

Create a mixture by combining 100ml of vinegar with the juice of one lemon. Spray this solution onto the toilet surface, allowing it to sit for 30 minutes. Afterward, flush the toilet and use a damp cloth to clean the exterior surfaces.

Bicarbonate and Hydrogen Peroxide
The combination of bicarbonate (baking soda) and hydrogen peroxide has the ability to whiten surfaces, making it ideal for darker limescale. Additionally, it has a disinfectant effect.

Mix 80 grams of baking soda with 2 tablespoons of hydrogen peroxide and use a sponge to scrub the solution onto the affected surfaces.

After 30 minutes, rinse thoroughly with water, and you will have a clean and pleasantly scented bathroom.
