What Is Hard Water And How To Remove Calcium Deposits?

Hard water is broadly defined as water that has a high mineral content – the hardness or softness of tap water will often vary across different regions.

With water flowing through our taps, into sinks, baths and toilets, the high mineral content found in hard water can have some irritating effects, such as calcium and magnesium deposits which build up and can be tough to remove.

What causes hard water?

Water is a solvent, and when it rains onto areas of porous, sedimentary rock such as limestone, chalk or sandstone, the rainwater dissolves the chemical compounds within it. These compounds typically involve calcium and magnesium. The chemicals then leech into lakes and rivers, and into our water supply. Our water supply then travels through the pipes in our homes and ends up in our kettles, baths and sinks.

What removes hard water deposits?

When planning to get rid of calcium deposits, we recommend having the following tools and products on hand:

  • A soft cloth
  • Harpic Bathroom Cleaning Spray
  • An old toothbrush (for hard to reach spots)

How to remove calcium deposits from tiles

The tiles surrounding your bath, shower and sinks are a typical spot for calcium deposits to build up. Before you start tackling the tiles, please ensure you have proper ventilation. Always spot check on a small/hidden area before using the product.

  1. Turn the trigger nozzle of the Harpic  Bathroom Cleaning Spray to the “ON” position.
  2. Directly spray the cleaner onto the calcium deposits and leave for one minute.
  3. Using the cloth wipe clean.
  4. Rinse roughly with warm water and wipe down with a damp cloth for a clean and shiny finish.

How to remove calcium deposits from faucets/taps

Knowing how to remove hard water build up from faucets/taps is critical because it can be a troublesome and unsightly area of calcium build up. To clean these tricky areas, follow the same instructions as you would for tiles, using  Harpic Bathroom Cleaning Spray and allowing the product to sit for one minute before wiping. Additionally, you may want to use an old toothbrush to allow you to rub the formula in to the difficult angles and crevices of the taps.

Though we cannot change the fact we live in hard water areas, by keeping a regular cleaning routine and using the right products, we can keep calcium deposits at bay.
