• Brand: Hercules®
A heavy-duty, sulfuric acid drain solvent formulated specifically for emergency use by professionals. Heavier than water, Clobber flows quickly to the blockage allowing special wetting agents to rapidly clear drain, sewer or waste line. It disintegrates paper, rags, sanitary products, grease, sludge, soap, fat, wood, hair, all types of food and organic matter. Clobber is formulated with 93% virgin sulfuric acid concentrate and additives that inhibit corrosive action on ferrous and non-ferrous metals. In an independent laboratory test*, Clobber was rated superior to similar type products in preventing corrosion. Because Clobber causes a significant rise in temperature when added to water, it can be used to thaw frozen lines. Will not harm septic tanks, cesspools, drainage fields and leaching systems when used according to directions. Clobber comes in a molded-handle plastic jug with child-proof caps preventing accidental openings. It is sealed in a plastic bag with warning tags. Jugs are packed in D.O.T. approved cartons. A SAF-T-POR spout is included with each 1/2 gallon jug of Clobber to permit safe, easy pin-point application without hazardous spilling.
