Prepare the Toilet
Flush the toilet to wet the bowl slightly, which helps the ingredients stick.
Apply Baking Soda
Sprinkle baking soda generously over the black stains.
Add Vinegar
Pour white vinegar over the baking soda. The mixture will fizz, helping to lift stains.
Optional Lemon Boost
Rub a cut lemon over the stains for added scrubbing power and natural antibacterial effect.
Scrub & Let Sit
Use a toilet brush to scrub the stains gently.
Let the mixture sit for 10–15 minutes for tough stains.
Flush
Flush the toilet to rinse away residue.
Repeat if necessary for persistent marks.
