I'll try not to waffle. I've got a TNF jacket, waterproof outer, down inner. The instructions on the label on both say to machine or hand wash in warm water with a mild detergent (not liquid) separately, rinse twice then tumble dry on low. Would you therefore wash both bits separately, which seems a bit when I could get both in the machine and done together... I wash ds's waterproof jacket in a solution called Granger's from an outdoors shop which was recommended, and I was going to use this on my jacket too - but then I've read that it does something to the waterproof lining, so do I wash the down inner, then put a separate wash on, wash the waterproof outer, then put a separate wash on and put ds's jacket in with the special solution? Anybody done this? Then I'll start on dh's 2-in-1!!
