4330-08 Nu-Calgon Scale Dissolver, Liquid 1 gal.

Nu-Calgon’s Liquid Scale Dissolver works faster and can be more economical than powdered acids. However, do not use liquid scale dissolvers on systems that contain galvanized, stainless steel or aluminum. The hydrochloric acid in these products could damage those and other soft metals. If one does not know what types of metals are in the system use Season Start. Both products include a built-in pH color indicator, which shows how much to use, when to add more, and when the system is clean. pH test paper is also provided.
