Profile: Fergin & Associates, Inc. produces a wide variety of environmentally safe cleaners and degreasers. We offer acid cleaners, asphalt release agents, defoamers, degreasers, alkaline/foam cleaners, oil separation cleaners, rust inhibitors, scum removers, and industrial plant cleaners. Our concentrated liquid acid cleaner is used to clean and de-rust iron & steel without attacking base metal which deposits a phosphate coating on the steel that retards flash rusting and promotes paint adhesion. Our non-polluting water based de-foamer controls all types of foam in sewage aerators, digesters, scum blankets, cooling towers, industrial cleaning operations, pulp & paper production, and in other applications, where foaming is a problem.
