The SUMMIT BRANDS IO65N is an all-purpose rust and stain remover formulated for use across a wide range of residential maintenance tasks. Supplied in a 76-ounce container, this powder-based treatment removes iron and rust deposits from laundry, porcelain surfaces, glassware, toilets, flush boxes, bumpers, and tools. It also serves as a dedicated water softener cleaner, clearing accumulated iron and rust from softener resin beds to restore efficiency. The IO65N contains no acid and is certified nontoxic, making it appropriate for routine use by service professionals and maintenance staff. It is sold as a single unit.
This product is commonly used by plumbing and water treatment service professionals during water softener maintenance calls, as well as by facilities and property maintenance personnel handling iron staining on fixtures and surfaces. In water treatment applications, regular use helps conserve salt, extends the interval between regeneration cycles, and prolongs the operational life of the softener unit. For laundry and fixture staining, it addresses iron deposits that standard detergents do not remove.
Designed for use with residential water softener systems and suitable for general rust and iron stain removal on common household and plumbing fixtures and surfaces.
Application is performed by plumbing professionals or water treatment technicians during scheduled softener service intervals or as needed when iron fouling is observed. Follow the product label dosing instructions for each application type, as water softener cleaner use and surface stain removal require different concentrations. Shut off the water supply to the softener unit before servicing the resin tank where applicable. Do not mix with chlorine bleach or other chemical cleaners.
