How Does Hard Water Affect Detergent?

How Does Hard Water Affect Detergent?For laundry, hard water has a damaging effect in general. LAS (Linear Alkylbenzene Sulphonate) is the primary surfactant used in laundry detergents (mainly in low-grade brands). This surfactant loses efficacy when used with hard water, which will result in lower performance.

To counter this issue, manufacturers add unique ingredients to the detergents. However, if the water hardness is extremely high, these special ingredients would not be sufficient to neutralize the Calcium (Ca) and Magnesium (Mg) ions in the hard water.

How to Choose the Best Detergent for Cloth Diapers in Hard Water?

1. Know the Hardness Level of the Water in Your Area

hardness in waterAs mentioned earlier, there is a level of water hardness in most regions of America. You can know the degree of hardness of water in your area through a water stripping test or in a pet store. According to the American Society of Agricultural Engineers, you can classify hard water as moderately hard, hard, and very hard. You can measure it in parts per million (ppm) or grains per gallon (gpg).

  • Moderately hard water measures 62 to 120 ppm or 3.6 to 7 gpg.
  • Hard water measures 121 to 180 ppm or 7.7 to 10.5 gpg.
  • Very hard water measures over 180 ppm or 10.5 gpg.

The best detergents for cloth diapers, especially on hard water, should able to neutralize the minerals and avoid redepositing them onto clothes. Also, you will know what to buy and how much detergent you need to use when you identify the level of hardness of water in your area.

2. Liquid vs. Powder

laundry detergent powder vs. liquidMost of the ingredients in powdered detergent attach to the minerals instead of cleaning the diaper when you are washing in hard water. This makes the detergent less effective.

  • A study revealed that the volume of powdered detergent needs to be increased when washing a standard soiled fabric in 100 ppm hard water to clean the fabrics effectively.
  • If the powdered detergent has a built-in water softness, you can reduce the amount of powdered detergent.
  • Liquid detergent performs well both in soft and hard water as the non-ionic surfactants that they contain make them resistant to water hardness.
  • Also, liquid detergents lack ionic groups, so they dissolve equally well regardless of the conditions and the water temperature, so liquid detergents are the best choice when doing cloth diapers laundry in hard water.
