The PreEmpt CS20 is a biodegradable chemo sterilant designed for the beauty industry for our tools. We must scrub the implements in the wash dilution with friction to remove the organic material, then rinse, then dry and then soak for 20 minutes. CS20 is not diluted. Only soak for 20 minutes. Remove implements, rinse, dry and bag or box until next use. You can only use stainless steel, nickel, glass, aluminum, metals and some resilient hard plastics that can with stand erosion. Do not get on the skin. Fill the soaker to the fill line enough to cover implements when immersed. This fill will last for 14 days and then must be replaced. Check expiry dates on the product and follow directions.
