rust is gone!  I have owned my home for 24 years and the Culligan water softener that is here was old when I bought the house. I have always had rust problems and when I have the water tested they tell me the water softener is doing all it could do. Then I found Crystal Clean. The people at Crystal Clean said that they were not sure that it would work on a 24 plus year old system. Well it did. My wife is blonde and she won’t do without Crystal Clean for her hair and white clothes.
