There is some risk involved in using any care process not recommended by the manufacturer. Hand washing involves manual removal of soils with water, detergent and gentle squeezing action. A care label that calls for machine washing, in a delicate or gentle cycle, indicates that the soil can be removed with water, detergent or soap, slow agitation and reduced time in a washing machine.
Hand washing is a restrictive care process that minimizes the abrasion a garment receives in cleaning. If hand-washable garments are machine washed in a gentle cycle, agitation may be further reduced by placing the item in a net bag. Even this procedure is in violation of the care label instruction and places responsibility on the cleaner rather than the manufacturer.
