• After transitioning from Sodium Chloride to Potassium Chloride, I have noticed a dramatic improvement in the softness of my shower water. Not only that, but using Potassium Chloride is much better for the environment than its sodium counterpart.
• Morton potassium chloride is the only brand of water softener salt that won’t damage your unit or plumbing. Unfortunately, due to high inflation, it’s becoming harder and harder to find in big box stores as they are stocking inferior products instead. Amazon was one of two places where we were able to find Morton at a reasonable price – although significantly more expensive than before – but still cheaper than replacing fixtures, heaters and other equipment damaged by low-quality salt.
• I was delighted to find a product that is nearly identical to the licorice I used to buy from Kroger, QFC, and Dillons in their produce section – it appears they don’t sell them anymore. Many thanks for providing this great replacement!
