- Significantly more effective than enzymatic cleaners in removing debris and bio-burden from evacuation lines. Vac Attak™ is especially effective on prophy paste and fluoride gels, the two most common causes of blocked lines. - Fast-acting organic chlorine formula facilitates the immediate breakdown of protein chains, found in bio-burden, into water-soluble amino acids. - Safe and environmentally friendly, non-corrosive to metals. Vac Attak™ is non-foaming and safe for use with all pumps. Prevents scale build-up in pumps that otherwise forms when using hard water. - Economical and easy to use, one scoop of concentrated Vac Attak™ dissolves quickly into 32oz (0.95L) of warm water and then is flushed through the system. It’s that easy! - - - Up to 100 cleanings per 800g jar. - Fresh lemon scent.
