Storage and Disposal
Store CLR PRO in its original container, tightly closed, in a cool, dry, well-ventilated area, away from direct sunlight and incompatible materials. Do not freeze. Dispose of unused product and empty containers according to local regulations and guidelines. Consult your local waste management authority for proper disposal methods.
