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 non-living organics. No more waterline rings, 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!
