The answer to 'how to clean toilet repair' is to first turn off the water supply to the toilet, then flush the toilet to empty the tank and bowl. Use a toilet brush and toilet cleaner to scrub the inside of the bowl, making sure to get under the rim. Use a rag or paper towels to wipe down the exterior of the toilet, including the tank, lid, and base. Finally, turn the water supply back on and flush the toilet to rinse away any cleaner.
It's important to clean the toilet regularly, about once a week, to prevent buildup and keep it looking and functioning its best. If you encounter any issues with the toilet that you can't resolve through cleaning, such as a clogged or leaking toilet, it's best to call a professional plumber for repairs.
