How to remove calcium deposits from pipes

Updated February 21, 2017

Calcium is a mineral that water can absorb through its trek from the source to the destination. When absorbed into the water, calcium as well as magnesium create mineral deposits and cause what is known as hard water. When the hard water travels through pipes to get into your home and provide you with clean water, it can be frustrating to find that the water is hard and makes cleaning nearly impossible. In severe cases of hard water, mineral deposits can form and block the piping that feeds the water into your home.

Drain all the clogged up or sluggish drains from excess liquid.

Pour one gallon of white distilled vinegar through the drain all at once. The acidity in the white vinegar will break down and melt all calcium build-ups inside the pipes.

Wait 30 minutes.

Stick the brush with the long handle into the pipes and scrub the area vigorously.

Rinse away the vinegar and install a hard water filter on your system.


If the white vinegar alone does not improve the condition of your drain, dump 1 cup of baking soda followed immediately by 2 cups of white distilled vinegar into the drain. The reaction of the baking soda with the vinegar will create a bubbling action that will successfully remove any clogging debris.

Things You'll Need
