To the washing machine !
in the washing machine, without complex, but softly. Choose a soft program, “synthetic” style, low temperature. Spin at minimum. The down jacket will be alone in the machine, with 2 tennis balls, just to stir the down during washing and spinning. Use your usual detergent (preferably soft), without softener.
Without complex! but gently, once again… Gentle programme, slow rotation. The comforter will be alone in the machine, again with 2 tennis balls. Repeat the operation 2, 3 cycles, and you will see your comforter regain its puffiness! When the dryer comes out, lay your down jacket flat and, with a soft stick, tap your jacket, in the height to make the down migrate and distribute the dry down. No balls of down should remain along the seams. If this is the case, go back to the drying area!
Without a tumble dryer?
If you don’t have a tumble dryer, you can of course dry your down jacket on a clotheshorse. This may take several days depending on the thickness of your jacket. Make sure your jacket is outdoors on both sides. Turn and pat your down jacket regularly, several times a day, to prevent the feathers from sticking together in small packets. Finally, lay your down jacket flat and, with a soft stick, tap your jacket from the top to allow the down to migrate and spread out when it is finally dry. No balls of down should remain along the seams. If this is the case, go back to drying! Never dry your down jacket on a radiator.
So that it regains its puffiness…
If you have stored it in its small bag, all compressed, your comforter will take “some time” to regain its puffiness, its volume. To find it back as quickly as possible, shake it a little so that it unfolds, then simply lay it flat, outdoors and in the sun. In absolute terms, in 3 hours, it should have regained its maximum volume …
