Hard Water

The Problems With Hard Water

Clothes washed in hard water often look dingy and feel harsh and scratchy. The hardness minerals combine with some soils to form insoluble salts, making them difficult to remove. Soil on clothes can introduce even more hardness minerals into the wash water. Continuous laundering in hard water can damage fibres and shorten the life of clothes by up to 40 percent.

Around the home

  • Crusty, white scale buildup on faucets, shower heads and water-using appliances
  • Dishwasher that no longer cleans dishes well
  • Reduced water flow due to clogged pipes
  • Hard-to-clean film and scale on bath and kitchen fixtures, shower walls and toilets
  • Spotty, filmy glasses and dishes—even after washing
  • Soap that refuses to lather no matter how much you use
  • Gray, dingy clothing
  • Towels that feel hard and scratchy after washing

Water Systems & Pipework

Hard water also contributes to inefficient and costly operation of water-using appliances. Heated hard water forms a scale of calcium and magnesium minerals (limescale deposits) that can contribute to the inefficient operation or failure of water-using appliances. Pipes can become clogged with scale that reduces water flow and ultimately requires pipe replacement.


When washing dishes, especially in a dishwasher, hard water may cause spotting and filming on your crockery. The minerals from hard water are released faster when it comes into contact with heat, causing an increase in the amount of spotting and filming that occurs. This problem is not a health risk, but it can be a nuisance to clean and reduce the quality of your crockery.


Bathing with soap in hard water leaves a film of sticky soap curd on the skin. The film may prevent removal of soil and bacteria. Soap curd interferes with the return of skin to its normal, slightly acid condition, and may lead to irritation. Soap curd on hair may make it dull, lifeless and difficult to manage.
