Launder items using hot water, regular amount of detergent, and 1 cup each of white vinegar and baking soda. Repeat if any smoke smell remains. DO NOT dry until smoke smell is gone. This worked beautifully on my daughter's garments after her apartment complex had a fire. Most loads had to be run twice.
You should not use baking soda and vinegar together, as they neutralize each other. From reading other posts regarding deodorizing, I would suggest the baking soda in the wash cycle and the vinegar in the rinse. Perhaps if you had used them separately, you would have only had to wash the clothes once.
