The answer to 'how to clean toilet repair' is to first turn off the water supply to the toilet, then remove the tank lid and flush the toilet to empty the tank. Use a toilet brush and cleaning solution to scrub the inside of the tank and bowl, paying special attention to the flush mechanism and any stains or buildup. Rinse the tank and bowl thoroughly and turn the water supply back on to refill the tank.
It's recommended to clean the toilet tank and bowl at least once a month to prevent mineral buildup and keep the toilet functioning properly. If you encounter any issues with the flush mechanism or other toilet components that require repair, it's best to call a professional plumber for assistance.
