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.


This product is designed for use in properly balanced spa water.

Initial Dose: Add 1 capful (4oz) per 400 gallons directly to spa water evenly around the edge immediately after the initial fill and after each drain and refill.

Weekly Maintenance Dose: Add 1oz per 400 gallons (one-quarter of the large-cap) weekly directly to spa water evenly around the edge.
