Rust Rid is a uniquely formulated water-based rust remover that exhibits a near neutral pH. Rust Rid is ideally suited for removing rust on cast iron alloys, tool steels, and all carbon steels. Rust Rid is most effective against surface and blush rust.

Rust Rid contains no caustic, toxic, or hazardous components. Rust Rid offers excellent wetting and defoaming properties allowing for uniform coverage on complex part geometries in immersion applications.

Note: For best results, it is recommended that Rust Rid be used in immersion baths for optimum exposure and coverage. In addition, if Rust Rid is to be used for extended periods of time, it should be used only in process vessels composed of plastic, fiberglass, or stainless steel alloys (316 stainless steel) to avoid potential chelation and staining of process vessel surfaces.

Although heat accelerates the rust removing ability of Rust Rid, it can be extremely effective at ambient temperatures if given sufficient concentration and processing time. For purposes of testing, evaluate Rust Rid at 15% to 25% in cold solutions and 5% to 20% in solutions at 140°F or 160°F depending on the substrate metallurgy and condition as well as the type and degree of corrosion being removed. Initial screening evaluations should be conducted in the lab prior to full-scale implementation under industrial conditions.

Rust Rid should always be added to the water in the system tank with mild agitation. Mild agitation during use will also improve performance. Filter accumulated rust from the system over time.
