Really Stubborn Stains: Pumice Stone (Yes, Really!)
A wet pumice stone (made for toilets—not the facial kind!) is safe on porcelain and glides away mineral buildup without scratching.
- Wet the stone and the bowl.
- Gently rub the stain in small circles.
- Rinse.
⚠️ Never use dry—it can scratch. Always keep it wet.
🚫 What Doesn’t Work (Or Makes It Worse)
-
- Bleach: Kills germs but won’t remove mineral/urine scale—and can even set stains if used alone.
- Commercial lime removers: Often contain harsh acids—effective but unnecessary if vinegar works.
- Scouring
