Pre-Drain System Scrub for Spas

SPA-500 is a concentrated cleaning product for spas. This is a unique product for Orenda, because it is not intended for use with bathers in the water. It is a powerful scrubbing formula designed to clean the spa and its internal system (pipes, jets, etc.) Follow directions on the bottle for a deep clean before draining and refilling your spa. SPA-500 includes our trademark enzymes to break down and digest non-living organic waste, leaving your system extra clean for refilling.
SPA-500 is NSF/ANSI Certified Standard 50
Made in the USA
