Add a capful or two of a gentle detergent, the kind you would use to wash delicate items by hand, into a basin or bathtub (always defer to the manufacturer's directions on the bottle).
Fill the basin or bathtub with cool water, and agitate it with your hand to mix the detergent and water.
Place the chenille throw into the bathtub or basin, and gently agitate the water again for five minutes.
Drain the soapy water from the basin or tub, and refill with clean, cool water to rinse the throw. Ensure all detergent is washed out of the throw.
Squeeze excess water from the throw, and place in a clothes dryer.
Set the dryer to a low setting, and let it tumble dry the chenille throw.
