1. Machine Washing
Add a cleaner specifically designed for down coats to the drawer of your front-loading machine. Select the delicate cycle and make sure to use cold water. Once the cycle is complete, transfer your coat to the dryer and dry it on low heat. For optimal drying, add 2 or 3 clean tennis balls or dryer balls. This helps to distribute the heat well and avoid clumps of down. Be patient, drying can take several cycles. It is important to make sure that the down is completely dry to prevent the insulation from retaining moisture. The dryer also helps to restore the fluffiness and insulating power of the down.
2. Cleaning Stains
Mix a little water with a specialized soap. Make sure to hold the outer fabric so that it is as far away from the down as possible. Use a soft cloth to gently rub the stains. Then, rinse the fabric without wetting the down. Once well rinsed, let your coat air dry.
3. Hand Washing
Fill your bathtub with cold water and then pour in a mild soap or a cleaner specifically designed for down. Completely immerse the coat and let it soak for 30 to 60 minutes. If there are any stains on the fabric, take the opportunity to gently rub them. Afterwards, empty the water and drain the coat as much as possible. Fill the bathtub with clean water again to rinse it. If necessary, repeat the process until there is no more soap. To wring it out, gently press on your coat, being careful not to twist or roll it. For drying, use a dryer to ensure that the down is perfectly dry.
4. Storage
If you are storing your coat after washing, make sure it is completely dry. Store it in a ventilated place and be careful that it is not compressed. Never store your coat in its compression bag. The latter should only be used to facilitate the transport of your coat.
The tips mentioned above apply to the majority of waterproof and down garments. That said, be sure to always read the instructions on your coat's label or on the manufacturer's website to make sure there are no contraindications.
