Why does soft water make my skin feel slippery, slimy, or I can’t get the soap off?
People who have had hard water all their lives are used to the feeling. In the hard water your pores are always clogged with soap scum. The same soap scum that is on the shower doors and walls. When this scum is packing your pores, your natural skin oils are not able to come out.
Showering or washing in soft water cleans your pores out and your natural skin oils are now able to come out. Remember what happens when water mixes with oil? It gets kind of slippery, or slick. That is the feeling that you are experiencing. For the first time your pores are no longer filled with soap scum and your natural skin oils are free to come out.
