Oatey HERCLOBBER12GAL Hercules Clobber Drain and Waste System Cleaner 0.5 Gallon Jug

Product Description

The Oatey HERCLOBBER12GAL Hercules Clobber Drain and Waste System Cleaner is a heavy-duty sulfuric acid-based drain cleaner designed for professional plumbers and maintenance technicians who need fast, reliable results on severely clogged drains and waste lines. This product comes in a 0.5 gallon jug and delivers industrial-strength clearing power that most standard drain cleaners simply cannot match. With a composition of 96 to 98.5 percent sulfuric acid and a pH of 0.9, this is one of the most aggressive liquid drain openers available to trade professionals. It is formulated specifically for use in drain and waste systems where organic blockages such as grease, hair, soap scum, paper, and food waste have built up over time. The extremely low pH means the sulfuric acid reacts rapidly with organic matter, breaking down obstructions through an exothermic chemical reaction that generates heat and dissolves the clog. This makes it especially effective in floor drains, kitchen sink drains, lavatory drains, and main waste lines that have become heavily restricted or fully blocked. Plumbers working in commercial kitchens, restaurants, multi-unit residential buildings, and industrial facilities will find this cleaner useful when mechanical snaking alone is not enough or when a fast chemical treatment is preferred. The liquid form allows it to flow directly through standing water and reach the blockage without dilution issues that affect lighter formulations. The dark brown liquid has a pungent sulfurous odor, so proper ventilation and personal protective equipment including chemical-resistant gloves, eye protection, and appropriate respiratory protection are required during use. This product should only be handled by trained trade professionals familiar with concentrated acid safety protocols. Always follow all safety data sheet guidelines and local disposal regulations when working with this product.
