Sleeping bags can be generally treated like any down or fiberfill garment. These items can be either drycleaned or washed, depending on the shell fabric. When drycleaning, avoid underloading or overloading the wheel. Underloading can increase the amount of agitation and contribute to shifting, and overloading can cause poor rinsing. Always use clean solvent and increase the extraction time.
Due to their thickness, you may be required to double the drying time. A clean pair of tennis shoes or some tennis balls may help to remove the solvent from the quilted areas during the drying cycle. Sleeping bags should be allowed to air out for at least 24 hours before returning them to the customer to ensure that there is no remaining solvent in the filler, and they should not be done on a one-day service. When washing, wash separately on a gentle cycle. Be sure to use a mild detergent and rinse twice.
