Staining in spas can be caused from metals or organics.
Metal staining can appear in color as: blue, green or black (copper), rusty brown or greenish/brown (iron).
Metals can enter the spa a variety of ways, however, the most common are:
Well water is usually high with mineral content and municipality water can have up to 1.3ppm of metals as allowed by EPA standards
A common source of copper in spa water enters from heaters that have been corroded due to keeping the pH level too low for extended periods of time
To identify a metal stain, gently hold a Vitamin C tablet on the stain & let sit for 1 minute. If the stain is removed or lightened by the Vitamin C tablet, then the stain is a metal.
To remove stains from a spa we recommend using our Stainfree Extra Strength along with our Spa Stain & Scale or Spa METALfree.
Stainfree Extra Strength is ideal for treating staining on all surfaces.
Spa Stain & Scale protects your spa from the damaging effects of scale build-up and staining due to excessive calcium, iron, copper and other minerals. It works without the use of phosphates or harsh acids.
Spa Stain & Scale also assists in preventing scale from forming on salt generator cells, therefore helping maintain optimum performance.
Spa METALfree is a highly effective metal deactivation agent that prevents staining and discoloration from trace metals such as iron and copper. Spa METALFree does NOT add phosphates to spa water.
Organic staining may be caused from a variety of sources, but the most common in spas occurs as the result of bather waste. Over time organics such as; cosmetics, lotions, body oils, hair products, etc., may cause these stains to appear. To identify an organic stain, hold a chlorine tablet on the stained area and let sit for 1 minute. If the stain is lightened by the chlorine, then the stain is caused by organics. If stains are caused from organics, we highly suggest using Spa Purge and Spa Perfect

Spa Purge attacks the root cause of most spa maintenance problems- the build-up of organic waste contamination! Organic contaminants collect and build up in your spa, circulation system, and filter. By purging the spa of this organic build-up, the symptoms of organic contamination will be reduced or eliminated.
Spa Perfect's patented formula establishes an active base of natural enzymes to aid in the breakdown of organic waste. It biodegrades body oils, cosmetics, suntan oils, and other organics commonly found in spa water. This helps to eliminate scum rings, reduce cloudy water, and allows for increased filter cycles in your spa.
