Hard water is a problem in many places across the country, more in some places than others. 

And while hard water may not be particularly dangerous to us, it does considerable damage to our home’s plumbing.

Hard water contains a large number of dissolved minerals, and these minerals leave behind deposits in your plumbing pipes, in your toilet bowls, and even on glassware.

These minerals may be sulfates, chlorides, calcium, and magnesium salts, among others. Calcium deposits are commonly found in toilet bowls, and make white toilet bowls look dirty by causing yellow or white deposits. 

Not only do these deposits make the toilet bowl look unhygienic, but they also can, over time, even erode the bowl itself. In addition, they also cause the water to look cloudy and can slow down the flushing considerably.

The longer you leave these mineral deposits to remain on your toilet bowl, the harder they will be to remove. This means you ought to ideally remove these deposits as soon as you notice 

them. In this short read, we’re going to discuss exactly how to do that.

Pre-cleaning prep

It is important to have easy access to the calcium deposits in your toilet bowl. To enable this, begin by turning off the water supply to your toilet bowl, and then flush the toilet once. This will reduce the water level in the bowl and expose the deposits at the bottom.

Check under the rim and the jets

Calcium tends to build up under the toilet rim and can even block the jets that allow flush water to access the bowl. Use either a pin or a wire coat hanger to poke the jets and remove any mineral buildup present there.

Washing the bowl

Liberally spray distilled white vinegar wherever there are deposits and let it rest for around an hour. Lemon juice works just as well in removing calcium deposits, being acidic in nature.

After letting it rest, scrub away at the calcification using a pumice stone or a stiff-bristled toilet brush. This should help get rid of the calcification.

Be sure to wear rubber gloves while working on scrubbing the toilet bowl.

If you still have any stubborn deposits sticking around, pour some baking soda onto the toilet brush and get to work on them. Old-fashioned elbow grease is the most efficient way to get rid of these stains.

Once the deposits have been removed, wipe the toilet bowl with a soft cloth to remove any deposits the pumice stone may have left behind. Then, turn on the water supply and flush the toilet clean.

Pro tip

The more often you clean your toilet, the less likely you are to have mineral deposits.

Clean the pipes

Next up, address the calcium buildup in the toilet pipes. To do this, pour a cup of distilled white wine vinegar into the toilet overflow tube in the toilet tank and let it rest for at least half an hour.

The acidic vinegar breaks down the mineral deposits and when you flush the toilet, it prevents calcium deposits from forming in the bowl.

Alternative cleaning products

If the deposits are very stubborn, you may need to use commercial cleaning agents, such as muriatic acid, or products that contain diluted hydrochloric acid. Remember to use rubber gloves and protective eyewear while handling these chemical cleaning agents. 

Preventive tips

Now that we’ve seen how to remove limescale, calcium deposits, and other minerals from the toilet bowl and pipes, here’s what you can do to prevent them from forming altogether.

  • Be sure to deep clean your toilet tank at least once every six months, if not more often. This prevents mineral deposits, algae, mold, and mildew and makes sure there are no foul smells.
  • If the water is very hard where you live, invest in a water softener. Water softening systems will ensure the minerals are removed before the water even enters the pipes, making sure you never have to deal with calcium deposits in your toilet bowl again
