How to Clean Blackout Fabric

Monica Patrick

Blackout fabric is used to make curtains and coverings that keep out light. Curtains backed with blackout fabric are perfect for a home theater or media room, where you can enjoy your favorite movies just as you would at a movie theater. Like any hanging curtain material, blackout fabric gets dusty and dingy looking.

Keep blackout curtains looking good.

Keep allergens at bay by cleaning your blackout fabric on a regular basis. This type of material is not suited for machine washing. Do your cleaning manually for the best results.


  1. Clean fabric on the rod with a feather duster.

  2. Stretch out the fabric on the rod.

  3. Sweep the duster back and forth in small strokes with your brush. Start at the top of the curtain and work downward.

  4. Lay fabric on a table. Use a soft cheesecloth to wipe the dust from the blackout fabric.

  5. Use a vacuum cleaner for an even deeper dusting. Attach the soft bristle attachment to the vacuum.

  6. Suction the fabric working from top to bottom in strips.


  1. Add a few drops of liquid dish detergent to a small bowl of warm water.

  2. Dip your cloth into the water. Wring the water out of the cloth.

  3. Blot up any stains by tapping the damp cloth on the spot.

  4. Warning

    Do not use bleach on your blackout fabrics. This will permanently discolor your fabric.
