Take the clothing items outdoors to a well-ventilated area. Put on a mask to prevent inhalation of the dust. Wear protective eyewear, as well.
Shake out clothing to remove excess dust.
Vacuum the clothing, using a vacuum-cleaner brush attachment.
Place the clothing in a container holding equal parts warm water and white vinegar. Allow the clothing to soak for one hour. The vinegar will help to clean the fabric and deodorize it.
Launder the clothing as you normally would, following the directions on the garment label.
