Shampoo can be used to hand wash garments, but it should never be used in a washing machine. It causes the machine to overflow with suds and may also ruin the clothes being washed.
Shampoo acts as a mild cleanser for delicate items, such as lingerie, hosiery and sweaters. Baking soda, borax and oxygen bleach are more effective alternatives to laundry detergent when washing very dirty clothes and removing stains. Use 1 cup of baking soda to wash a full load of laundry, or add 1/2 cup of baking soda or borax to an almost empty container of laundry detergent.
