If that odor is really stubborn (think musty attic or grandma’s perfume explosion), you need a pre-soak. Fill your bathtub with cool water, add a cup of baking soda and a cup of vinegar. Let your blanket soak for an hour, then wash as usual. This is the nuclear option—and it works.
Pro tip: Never use fabric softener on a blanket with tough smells. It just coats the fibers and traps the stank. Leave the softener for socks, not for your cozy throne.
Don’t Forget the Dryer!
After washing, dry your blanket completely—even a tiny bit of dampness invites sour smells back. Toss in a couple of wool dryer balls (bonus: they reduce static and save energy). If you must use a dryer sheet, pick one with a light, natural scent. Overpowering perfume just masks the problem.

And if you’ve ever thought “I’ll just let it air dry in the bathroom”? Stop that right now. Bathrooms are mold’s happy place. Dry it outside or in a well-ventilated room.
