6.1.10 Redeposition

Soil, dyes, and cleaning aids may be transferred to fabrics during laundering or drycleaning, causing white or light colored fabrics to become gray, yellow, or off-white. Laboratory tests for redeposition include localized stain removal and microscopic examination. If redeposition is uniformly distributed or if it is confined to an area where stain removal was carried out prior to cleaning, the fault is with the cleaner. If only specific panels or sections of the article are affected, involving fabric from two different bolts, redeposition is the result of a soil attracting characteristic of the fabric in the affected part, and is considered a manufacturing problem.
