This test was performed with 100% cotton cloth diapers. Poor rinsability was indicated by a weight gain after controlled washing and drying. Diapers washed in Tide Liquid (at recommended levels) gained nearly 2% in weight after only 8 washings. Those washed in Charlie's Soap (at recommended levels and 4 times recommended levels) gained no measurable weight at all. It is reasonable to assume that hypo-allergenic fabrics washed in Charlie's Soap Laundry Liquid, which is shown to leave no irritating residues, will surely remain so when washed with Charlie's Soap.
