FOR PROFESSIONAL USE ONLY.  This is a liquid, virgin-acid drain and pipe conditioner that dissolves organic residues in drains and waste pipes.  Eliminates stoppages quickly and easily and restores the minimum safe diameter (MSD) in drain lines by removing soap, grease and soft scale build-up.  Heavier than water, it goes down through the water to the point of the obstruction.  It contains an inhibitor that slows down the reaction so that surface "flashback" is eliminated when used as directed. Safe to use on all plumbing fixtures when used as directed. Ready To Use. This product requires an additional shipping charge.
