Lime softening (also known as lime buttering, lime-soda treatment, or Clark's process) [1] is a type of water treatment used for water softening, which uses the addition of limewater (calcium hydroxide) to remove hardness (deposits of calcium and magnesium salts) by precipitation.
The surface of human skin has a light charge that the soap tends to bind with, requiring more effort and a greater volume of water to remove. [4] Hard water contains calcium or magnesium ions that form insoluble salts upon reacting with soap, leaving a coating of insoluble stearates on tub and shower surfaces, commonly called soap scum.

“Hot water, like cold water, can be uncomfortable and promote burns,” Malin says. “Temperature in many studies tends to be near 104 degrees Fahrenheit, but going well above that should be ...
Designated as an American National Standard, the Uniform Swimming Pool, Spa and Hot Tub Code (USPSHTC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation and inspection of plumbing systems associated with swimming pools, spas and hot tubs as a means of promoting the public's health, safety and welfare.
Hot tub water temperatures should never exceed 104 degrees Fahrenheit, the CPSC noted, adding that soaking in water above that threshold can raise human body temperature to the point of heat stroke.
The hardness level of the water, measured as the amount of dissolved calcium, is also important. Insufficient hardness can lead to corrosion and water foaming. The ideal range of calcium hardness levels in a hot tub or spa water should be between 150 and 250 ppm (parts per million) [citation needed]
This water-resistant lantern-and-power bank combo provides bright, adjustable light when darkness falls. And it doubles as a power bank to charge your devices during outages.
As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental testing and is thus disproven. Any products claiming to utilize magnetic water treatment are absolutely fraudulent. [1]
