Helps Protect Against Metal Staining
Spa Metalfree is a highly effective metal chelating agent that protects against staining and discoloration from trace metals such as iron and copper. Spa Metalfree should be used as part of a well designed spa maintenance program. Spa Metalfree does not raise phosphate levels in spa water like many other stain and scale products.
Note: This product can be used with most sanitizing systems and is compatible with all spa surfaces. Do not use with biguanides.
