Why does your dishwasher get limescale? 

Excessive use of dishwashers combined with soap & water is mandatory if you have to remove the stains and spots from any used utensils. In some areas, water procured from natural sources contains lots of dissolved minerals and salts like calcium, sodium, potassium, carbonates, and chlorides, etc. These suspended particles have properties to adhere to any surface they come across. With repeated use, they start to form a solid layer along the inner walls of the dishwasher or the draining system. This layer is called hard water buildup; it looks like a grayish or white residue. These mineral deposits along with soap residues need to be removed regularly to keep your dishwasher clean and fresh.

Is calcium buildup bad for your dishwasher

Calcium buildup, also known as limescale deposits, does not contain any lime in them. Calcium buildup occurs in those homes where you have hard water. Hard water is the kind of water which is saturated with minerals, such as calcium. Over time, the inside of your dishwasher, as well as the other running parts of the dishwasher, start to get calcium buildup or deposits.

Calcium buildup can be hazardous for your dishwasher. The buildup can cause the water in your dishwasher to drain far more slowly. This will cause the motor to work much harder to get rid of the water. Over time, the dishwasher’s motor starts to degenerate.

The calcium buildup also causes the metal portions of your dishwasher to rust and can cause failure of these parts, such as the heating elements, the pumps and the motor of your dishwasher.

Calcium buildup also causes a cloudy, white residue to form on your dishes which are hard to remove, even after running them through the dishwasher. While this is aesthetically displeasing, it can also be quite harmful if ingested by you or your family. It is always recommended to remove the calcium buildup and deposits from your dishwasher for the safety of your dishwasher as well as your home.

How often should you remove calcium buildup

Preventing calcium buildup is as essential as removing them from your home. When it comes to eliminating calcium buildup, there are several sprays that you can use, such as vinegar and water sprays or even commercial sprays, which you can regularly use each day or every alternate day to remove as well as prevent future calcium buildup.

As for descaling, you can do this at least once a week. You can also remove permanent limescale removers which will work with every wash of your dishwashing cycle, thus preventing and removing calcium buildup regularly.

Remove calcium buildup from a dishwasher with white vinegar

The simplest way to keep your dishwasher impeccable is to clean it with white vinegar regularly. Here is how to do it:

What you need:

  • White vinegar
  • Drinking-glass or dishwasher plastic cup

Instructions:

  1. Remove all utensils out of the dishwasher before doing this.
  2. Now take 2 cups of white vinegar in a dishwasher safe glass. The quantity of white vinegar can slightly vary according to the size of the dishwasher tub. However, you should always try to use the recommended amount.
  3. Put the glass containing vinegar on the bottom rack and shut the dishwasher’s door properly.
  4. Then switch on the dishwasher on normal/regular wash cycle mode.
  5. Once the process is complete, wipe the tub from the inside using a soft cloth and leave the door of the dishwasher open for some time to let the smell of the vinegar and calcium residues disappear.

Warning:

  • You should not use more than the recommended quantity of vinegar for cleaning the dishwasher. Excessive use of acetic acid (vinegar) can damage the metal wall of the dishwasher.
  • Never use vinegar in combination with other cleaning agents like dishwasher detergent.
