Spa Perfect cuts cleaning and scrubbing by 50% or more and saves money too! Spa Perfect's patented natural enzyme and botanical extract formula powerfully yet gently biodegrades body oils, cosmetics, suntan oils, and other organics. No more scum lines, clogged filters or cloudy smelly water. Spa Perfect is also a continuous cartridge filter cleaner. Spa Perfect is now formulated to eliminate and prevent excessive foaming. No brown bubbles- just clear, sweet smelling water. Spa Perfect is 100% biodegradable. It contains no manufactured enzymes so it is non-toxic and non-irritating to skin, eyes, and mucous membranes. It is environmentally better!
