When reading the skin care regimens I noticed many use a knife to get the scales off. What my son has been using for years with great results, and much safer than a knife, is a plastic putty spatula. It has an uneven edge, and lifts up the scales easily. Recently though he began doing the salt bath soaks, and the scale buildup is decreased dramatically. I think now he is just using a wash cloth. I am truly amazed at the difference the salt baths make. So far he has been using regular table salt, but I have ordered some dead sea salt that I must just add with the table salt. At my local Smart N Final you can get a 20 pound bag of table salt for around $5.00. The dead sea salt with cost me $70.00 for the same amount. I want to see if the minerals in the dead sea salt make a bigger difference.
