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.

A detergent dispensing cartridge for use in a washing machine. The washing machine is for cleaning a soiled substrate. The treatment of the moistened substrate is with a formulation comprising a multiplicity of polymeric particles. Said formulation is free of organic solvents.

A cleaning system for laundry which includes a washing agent and a protective agent. The washing agent is configured to remove unwanted matter from the laundry. The protective agent is configured to create a bonded barrier comprising organosilane antimicrobial(s) on the laundry for protection against odors from bacteria, mold and mildew and/or the like. The washing agent and the protective agent are configured to be used in a two-step water-based treatment process in which the washing agent is provided in a given first step of the treatment process and the protective agent is provided in a given subsequent second step of the treatment process.

A method of washing a fabric is disclosed comprising the following consecutive steps: (i) performing at least two pre-washing cycles, wherein each pre-washing cycle comprises, washing said fabric with water at room temperature for 3 to 10 minutes, and draining the water for 2-10 minutes, thereby draining at least 30% of water volume; (ii) washing the fabric with a solution comprising water and detergent for 50 to 90 minutes at 35 C. to 90 C.; and (iii) performing at least three detergent-free post-washing cycles, wherein each postwashing cycle comprises, washing said fabric soaked with water at room temperature for said 3 to 10 minutes and draining the water for said 2-10 minutes, thereby draining at least 30% of said water volume.
