I was out of my regular water softener salt and reluctantly bought Morton's System Saver II as a substitute. The company adds an additive in the product to help clean the water softener. It doesn't disclose anywhere on the bag or the website what that additive is. A few days after I put the salt in the brine tank, I began to get rash-like hives all over exposed parts of my body in the middle of the night. I woke up to itchy hive like allergic reactions. These were clearly not insect bites. To be sure, I washed the sheets without any detergent or fabric softenener and still the allergic reaction continued. When I wear clothes washed prior to using System Saver II, the rash does not occur. Coincidence? I don't think so. The company is aware that it's product can cause itchy skin in some of its users.
Excerpt below from:
After using Morton water softening products why does my skin itch?
The additives used in Morton® System Saver® II or Morton® Rust Remover are normally removed from the water system during the brine and rinse cycle of the regeneration process. Even though it is unlikely that the additives in the salt product could be the cause of the skin itch, you may wish to try a product with no additives, such as Morton® White Crystal® products or Morton® Potassium Chloride Pellets. It would be prudent to consult with a dermatologist
Monetary Loss: $10000.
Preferred solution: The company should voluntarily inform consumers on the bag and website that use of the produce may result in itchiness and allergic reactions..
