Hard water stains in your toilet create unsightly brown, gray, or rust-colored rings that make even clean bathrooms look neglected. These mineral deposits form when calcium, magnesium, and iron-rich water evaporates, leaving behind stubborn buildup. The good news? With the right techniques, you can remove these stains and restore your toilet's shine.
What Causes Hard Water Stains in Toilets?
Hard water contains high levels of dissolved minerals. When this water sits in your toilet bowl, evaporation leaves behind deposits that create:
- Brown or rust-colored rings at the waterline
- Gray or white chalky buildup on porcelain surfaces
- Rough, scaly texture that attracts more dirt
- Discoloration that worsens over time
