Know before you buy
For optimal protection against staining and scale, you should apply this product weekly as part of your regular maintenance routine.
No, this specific formula is not compatible with saltwater systems. It is designed for use with traditional spa sanitizing methods.
Yes, the phosphate and acid-free formula is safe for all spa surfaces, including acrylic, fiberglass, and tile.
Spa METALfree is primarily a preventative agent that chelates metals to stop staining and discoloration before they occur. While it helps maintain a pristine environment, it is not intended as a heavy-duty cleaner for deep-set, pre-existing stains.
Every time you add fresh water to your spa, you may be introducing new trace metals like iron or copper. Using this product regularly ensures those new minerals are deactivated before they can settle and cause staining or scale build-up.
