Abstract

Linen treatment compositions and linen processes are disclosed which help to prevent iron deposition from wash water, and/or redeposition after iron containing stain (such as blood) removal by alkaline detergents. The linen treatment composition is a combination of a hydroxycarboxylic acid and an acid source, which may be organic or inorganic. The invention provides for effective iron control in a phosphorus-free formula that is also free of toxic or hazardous chemicals and includes sustainable, environmentally friendly ingredients, while still providing effective iron control.
