  • Funnel
  • Baking soda
  • Bucket
  • Toilet Brush
  • Tissue paper or cotton
  • Duct Tape
  1. Stop the water supply to the tank.
  2. All protective measures such as eyeglasses, gloves, and a respirator.
  3. It takes time to dilute the acid in water
  4. One cup of Muriatic acid, 10 portions (or more than half a bucket) of water
  5. Slowly pour the mixture into the funnel’s overflow tube.
  6. Tape all the duct tape to the siphon jet. Flush once
  7. Muriatic Acid will break down all crystals and sediments.

The solution pH balance should be acidic when using Muriatic Acid. Do not use a solution that is too acidic for the septic tank.

Acid destroys good bacteria and enzymes that are responsible for the human waste breakdown.

Before flushing, add baking soda to make the solution neutral. How do you determine if the solution pH is neutral?

You can see the formation of bubbles when you add the baking soda. These bubbles will form when the pH becomes acidic. When you add baking soda to it, the solution stops producing bubbles. This neutral solution is safe for your toilet.

Wrapping Up

Limescale is the leading issue when it comes to toilets. Hard water, which increases the limit of minerals causes limescale to build up.

Iron, calcium, and other hard water minerals can build up over time, causing small crystal particles to settle at the tank, siphon jets, or toilet base.

You can either replace your water softener or increase the filtration rate to prevent this from happening. Additionally, you can do a deep clean at home every once or two weeks to remove limescale from your toilet. You don’t have to spend a lot of money on commercial products.
