Hard water's effects on soaps & detergents.


The Detergent savings study & the Laundry study on hard water.

In 2010 the Scientific Services Laboratories located near Middletown, NY, was funded by the WQA to complete two comprehensive case studies to determine the effects that hard water has on household soaps, detergents & laundry washing. These two studies investigated stain removal properties on clothes & evaluated the effectiveness of detergents in dishwaters with an additional focus on spot & film evaluation.

The studies conclusively proved that a reduction in water hardness alone is up to 100 times more effective at removing certain stains from clothes then by increasing detergent dosage or water temperature. This was stated as being "The most significant conclusion of the study."

Softened water halves your detergent usage.

50% less washing powder & cleaner clothes.

The laundry study concluded that switching to softened water will improve laundry cleaning performance & help decrease your combined energy & detergent bills by at least 50%. This is true for both top loading & front loading washing machines.

For example, when using softened water for washing, the study showed that you will achieve better cleaning results on a cold laundry wash using half the detergent dose than if you were washing with hard water on a hot wash using a full detergent dose.

70% savings on Dishwasher detergents.

The dishwasher study presented statistically significant data showing how softened water benefits dishwashing performance & can reduce your detergent usage by as much as 70%.

Removing hardness from water was shown to be around 12 times more effective at removing soils, 6 times more effective at reducing spotting & twice as effective at reducing filming than increasing detergent dosage. Dishes were also shown to be streak free after air drying & this was noted as being another potential cost saving benefit.
