Deep stain.
I left this jacket in the car over a weekend and it turns out a travel mug filled with a coffee/sweet hot chocolate mix spilled on the shoulder just before I left and when we returned the shoulder was still soaked (liquid on the pooling on the surface). Now I understand this coat isn't water proof, so I'm assuming that the coffee/coco seeped into the down... Now that it's dry, what should I do. I want to avoid washing the coat if possible since it sheds down quite a bit... will the "dirtied" down be less insulating? Would it help if I just the shoulder in water and let it dry?
Thanks!

I take my down sleeping bag to the local cleaners, there they professionally wash it,and it looks beautiful when I get it back,Just like new. I don't wash it my self because I worry I would destroy the bag,,,,Its cheap enough to have them do it and if they destroy it there responsible to replace it,,,So I have no worries. Shane A

Your down garment can be professionally washed, but should never by dry cleaned, because the chemicals used are harmful to the fabrics and filling and will severely reduce loft and thermal efficiency. Check the yellow pages under Camping, Backpacking, or Mountaineering Equipment for folks who specialize in cleaning outdoor products. Your local retailer may also be able to refer you. Be sure to ask if they specifically wash down clothing. DIY Machine Wash: Zip up all the zippers, attach all Velcro® and turn your garment inside out. Wash in a front-loading machine only, using cold water on a gentle setting. Use a minimum amount of a mild powder soap or special down soap (available at outdoor stores). Use at least two rinse cycles to get all the soap out of the garment. When moving your garment from the washer to the dryer, do so carefully by carrying it from the bottom. Tumble dry in a large commercial dryer on low heat. The dryer must be large enough for the garment to flop freely around. Drying could take several hours and your garment should be checked often to make sure it is not overheated. As it dries, look for clumps of wet down and gently shake to redistribute the down. Do not use a top-loading washing machine (the agitator will destroy the channels). Do not use liquid soap or detergent. Do not use strong soap or detergent. Do not use your home dryer (they have been known to melt holes in the fabric). Do not lift your garment from one end when wet (lift the entire thing all at once from underneath). Do not dry in the sun (the UV will damage the nylon). Hope that helps. :)
