How to Remove Toilet Tank Stains

Over time, minerals in the water can leave a build-up inside of the toilet tank. Though often these are not harmful, they can be annoying when trying to clean. A simple acid-based cleaner will quickly remove any mineral deposits and leave the tank looking clean and fresh.

• Vinegar
• Coca Cola
• Bar Keepers Friend Powder
• Soft Scrub with Bleach
• Scrub Free
• Scrubbing sponge or toilet brush

1. Begin by turning off the water and flushing the toilet to drain the tank completely.
2. Next, fill the tank with vinegar or Coca Cola. The acid in either of these will loosen the mineral deposits and make them easier to remove.
3. After allowing it to set overnight, flush it away.
4. Use the scrubbing sponge to scrub the sides of the tank to remove any remaining stains.
5. Repeat as necessary.
6. A second method involves applying a series of cleaners. If the stain is removed early in the process, there is no need to continue with the remaining cleaners.
7. Start by turning off the water and flushing to empty the tank.
8. Use the scrubbing sponge to apply a layer of Soft Scrub. Allow it to soak and then scrub.
9. Rinse away with water and flushing.
10. Next, apply a layer of Scrub Free. Again, allow it to soak and then scrub the stain.
11. Rinse away with water and flush it away.
12. Last, apply the Bar Keepers Friend Powder and scrub with the sponge.
13. Allow it to set on the stain and then rinse and flush away.
14. Repeat any of the above steps if necessary until the stain is completely removed.

• If you have a private septic tank, avoid using too many bacteria-killing cleaners (such as bleach). These septic systems require bacteria to effectively destroy the waste. Instead, use cleaners such as Rid-X that keep the needed bacteria in the system.
• If rust is a problem, there are rust removers available at nearly every store that sells toilet bowl cleaners.
• If the toilet is vitreous china, you can scrub the stains away with a pumice stone. Do not use these stones on colored, enamel or plastic toilets.
• It is recommended that you clean the inside of the toilet tank twice a year.
