The answer to 'how to maintain toilet' is to perform regular cleaning, inspection, and minor repairs to keep your toilet functioning properly. This includes flushing the toilet regularly, cleaning the bowl and tank, checking for leaks, and addressing any issues promptly.
Start by flushing the toilet at least once a week to clear out any debris or mineral buildup. Use a toilet brush and cleaning solution to scrub the inside of the bowl, paying special attention to the rim and under the rim where grime can accumulate. Wipe down the exterior of the toilet, including the tank and base, with a damp cloth or disinfectant wipe.
