Granger's Down Wash
Granger's down wash is specially formulated soap for washing your down sleeping bag and down clothing items. Normal soap can strip down of its natural oils, so you should only use soap made for down products.
Sleeping bags do not need to be washed very often. Wash once after a long season or only as needed. This container is enough for one wash.
Be careful of machine washing down sleeping bags. The twisting motion of a washing machine could potentially tear the shell or the internal baffles. If you do try a washing machine do so at your own risk using the delicate setting.
We recommend hand washing your sleeping bag in a bathtub with warm water and Granger's Down wash. Keep the sleeping bag in the dry bag and remove it while it is underwater so that it doesn't fill up with air. Swish the bag around for a few minutes. Drain the tub then give it another good rinse in fresh water.
Squish the sleeping bag back into the dry bag and squeeze as much water as you can out of it.
For best results, lay the sleeping bag out in the sun to dry. If the sleeping bag has a darker shell material (for example black on the inside) face the black side up to absorb more heat from the sun. You will have to periodically pull apart any wet down clumps. It may take all day to completely dry a sleeping bag, but don't worry, eventually all the clumps will be broken apart and dry and it will fluff back up better than new.
Some people use a clothes dryer with tennis balls to help break the down clumps apart, but do so at your own risk. High heat can melt delicate shell materials. Even with a dryer it can take a very long time to dry a sleeping bag. We recommend drying your down gear items in the sun, or line drying indoors if outside weather doesn't permit sun drying.
