Rid-O-Rust, sometimes stylized as Rid O'Rust, is available from a number of retailers including Pumps N Parts LLC, USWaterSystems.com, Amazon.com and CleanWaterCart.com. The product's parent company, ProProducts LLC, also sells it directly to professional contractors and distributors.
The Rid-O-Rust brand name is attached to both a line of rust stain removers and rust stain prevention products. The stain removers are industrial strength, designed to remove rust stains within seconds. They are available in both powdered and liquid formulations. Stain prevention products are concentrated, designed to be mixed with water in the feeder system before taking effect. Therefore, they are for irrigation use only.
ProProducts LLC uses the brand name American Hydro Systems to market Rid-O-Rust. The same parent company also produces similar products under different brand names, including Pro Chemicals, LanoSoft, Spectrum and Red-B-Gone.
