Sani Vac Evacuation System Cleaner, 1:100 Dilution, 1 Gallon. Low-Foaming formula includes multiple proteolytic enzymes that efficiently remove a wider range of dental debris than surfactants alone as they specifically break down proteinaceous materials (saliva, mucus and blood) that build up and block evacuation lines. Phosphate-free, lemon scented, pH: 7.8 (prepared solution), biodegradable formula. Ideal for use in both wet/dry vacuum systems and amalgam separators.
