- 1). Pour 1 cup baking soda into your one-piece Toto toilet and scrub with the toilet brush.
- 2). Fill a spray bottle with distilled white vinegar and spray the entire inside of the toilet bowl. Treat the walls of the bowl thoroughly, and let the vinegar stand for one hour. This gives it time to break up any residue stuck to the walls as it works its way down to the bottom of the one-piece Toto toilet bowl.
- 3). Scrub the one-piece Toto toilet with your bowl brush again, then flush it. The vinegar and baking soda mixture kills bacteria and odor, keeping the toilet clean and free of foul smells.
