Instructions
Place the hard water in a large pot. Place the lid on the pot, so that less water is lost through evaporation during the boiling process.
Turn on the stove to the "high" setting. Allow water to come to a boil.
Boil the water for at least 10 minutes.
Turn off the heat and allow the water to stand until lime particles are visible on the surface of the water. Do not wait so long that the particles start to sink to the bottom of the pot.
Scoop the lime particles from the surface of the water using a large spoon. Throw them away.
Use the softened water for cleaning, brushing your teeth, bathing or drinking.
