Cleaning method

摘要

The invention provides a method for cleaning a soiled substrate, the method comprising the treatment of the moistened substrate with a formulation comprising a multiplicity of polymeric particles, wherein the polymeric particles are applied in combination with a detergent formulation, the method being characterized in that the detergent formulation is divided into its separate chemical constituents and these chemical constituents are added at different times during the wash cycle. The method allows for improved cleaning with reduced overall chemical loading, and facilitates addition of the more expensive parts of the formulations when they are most effective for cleaning performance, thereby providing considerable cost savings in comparison with conventional all-in-one detergent formulations. A method for cleaning the polymeric particles is also provided.

主权项

1. A method for cleaning a soiled substrate, said method comprising the treatment of the soiled substrate with a formulation comprising a multiplicity of polymeric particles, wherein said polymeric particles are applied in combination with a detergent formulation, characterised in that said detergent formulation is divided into its separate chemical constituents, wherein the chemical constituents comprise cleaning components and post-treatment components; wherein the post-treatment components comprise at least one component selected from the group consisting of anti-redeposition additives, perfumes, and optical brighteners; and wherein the cleaning components are added before or during the main wash cycle and the post-treatment components are added as a post-treatment following removal of the polymeric particles from the wash process.
