Matt paint is used to provide a smooth, slightly reflective coat to walls, cars, wooden furniture and other paintable objects. A matt coat does not have the highly reflective properties offered by a glossy coat, nor the dull plainness of a flat coat. Most matt paints are made with acrylic, which means that they are water-soluble and relatively simple to clean up. However, if the matt paint has dried and hardened onto fabric, its removal may require a bit more work.
Saturate the matt paint stain with a light solvent, such as isopropyl alcohol (at least 70%) or white spirit.
Allow the solvent to soak the stain for 10 to 20 minutes. This will begin to dissolve the hardened paint and make it easier to remove.
Scrub the affected area of the fabric with a bristled scrub brush. Use a firm, circular motion.
Rinse the fabric with fresh water and apply several drops of dish soap.
Clean away any remaining matt paint by working the dish soap into a rich lather with your scrub brush.
Rinse with fresh water once again and allow the fabric to dry.

Avoid using paint stripper or thinner on fabric, as this may cause permanent damage to the article of clothing.
