ABSTRACT:
The present invention relates to a composition and method for opening clogged drains. Specifically, the liquid drain opener composition of the present invention comprises about 70%-93% by weight sulfuric acid; about 1%-23% by weight water; about 0.01%-5% by weight of at least one corrosion inhibiting agent; and, about 0.01%-28.99% by weight of at least one surfactant. The drain opener composition may also contain mineral oil and inert filler materials, such as salt. The present invention is also directed to a method of opening clogged drains comprising the steps of contacting a clogged drain with the liquid drain opener composition of the present invention; the composition applying a protective coating to metal surfaces of the drain to substantially prevent corrosion of the metal; the composition applying a protective coating to concrete surfaces of the drain to substantially prevent erosion of the concrete; and, flushing the dissolved clog with water.
