Signifikant results require suitable testing methods.
The classic water-hardness measuring equipment indicates the same hardness in Whirlator water as in raw water. This is due to the indicator chemicals, which only detect the calcite crystals formed (consequently, aragonite is also identified as such). BUT the treated water shows all the known effects of soft water, e.g.
• the white stains (limescale) on tiles, faucets and other surfaces can be wiped off – without much effort or cleaning agents – like dry powder
• Soap foams more when washing hands
• Dishwashers and washing machines need less washing-up liquid and detergent
A simple test of the effectiveness can be carried out by boiling treated Whirlator water in a pot. The resulting residue (limescale) does not form solid deposits, but can be easily removed by wiping out the pot.
