I had a fire once. The company that takes the smoke out missed a coupla things...they still had the smell in them. I put the clothes in the washer, filled the washer with water added baking soda (about 1/2 box) and let it agitate. Once I felt the soda was mixed in good, I shut off the washer and let it sit for a few hours. Then drained the washer and washed in normal manner. The clothes smelled just fine after that!
Glad everyone was okay.
