Every completed Brazilian Embroidery stitched project should be laundered. The blue, water soluble, ink needs to be washed out along with hand oils that will attract soil as time goes by.
Hand washing is recommended.
Soak in warm water with mild detergent for 15 to 30 minutes to get the ink, hand oils and other dirty spots started on their way out. Then rinse and place the embroidered piece in warm water again with detergent recommended for colored clothes for at least a couple of hours. For exceptionally soiled areas, gently rub with your finger tips. Avoid bleaches or stain removers for they may whiten your threads or leave a lighter spot on your fabric. Soaking and rubbing gently with your finger tips will remove most stubborn stains.
