Step 1: Preparation

Start by turning off the water supply to the toilet. Locate the water shut-off valve, typically located near the base of the toilet, and turn it clockwise until the water flow stops. Flush the toilet to remove as much water as possible from the tank.

Step 2: Cleaning Solution Preparation

Create a cleaning solution by mixing equal parts white vinegar and water in a spray bottle or a bowl. Vinegar is a natural disinfectant and will help dissolve mineral deposits and kill bacteria inside the tank.

Step 3: Cleaning the Tank Interior

Spray the cleaning solution generously inside the tank, ensuring all surfaces are covered. Pay particular attention to areas with visible stains or mineral buildup. Let the solution sit for approximately 10-15 minutes to allow the vinegar to work its magic.

Using an old toothbrush or scrub brush, gently scrub the interior surfaces of the tank, focusing on areas with stubborn stains or mineral deposits. Be thorough but gentle to avoid damaging any components.

Step 4: Tackling Hard-to-Reach Areas

For hard-to-reach areas such as corners or narrow crevices, dip the toothbrush or scrub brush directly into the cleaning solution and scrub vigorously. Take your time to ensure all surfaces are thoroughly cleaned.

Once you are satisfied with the cleaning, turn on the water supply to the toilet and allow the tank to fill up. Flush the toilet a few times to rinse out any remaining cleaning solution. Use a clean cloth or sponge to wipe down the surfaces inside the tank, removing any residue or excess moisture.

Step 6: Final Checks

After completing the cleaning process, conduct a final inspection to ensure all areas are clean and free from stains or deposits. If necessary, repeat the cleaning steps to achieve optimal results.

While cleaning, inspect the tank for any signs of leaks or damage. Promptly address any issues to avoid water wastage or further complications.
