I don’t see a place to ask short one-off questions of the OMD collective (point me to it if there is a thread I didn’t see!).
Tl;dr Question: Should I get my down comforter professionally cleaned?
Backstory - Inside fill is Canadian duck down in sealed cover. It has always been covered with a duvet cover (which does get regularly laundered). It has not been shared with puppers. It has no noticeable odors or problems, though I’ve recently suspected that my bedroom isn’t ventilating as well as it should.
Officially, the comforter says dry clean only. I’ve owned it for 5.5 years now (used about 50-75% of the year) and have never had that done. Internet opinions range from clean it 1-2x/per year to every 3-5 years to 7-10 years to never. Internet also disputes whether you should have professional dry clean vs. professional laundering (not dry clean!) vs. DIY with commercial sized laundering equipment.
In hindsight, I also realize that the appropriate time to be airing it out and/or laundering is during hot/dry weather. Ooops.
