Acrylic paint is difficult to remove from textiles. Ideally, the paint stain should be treated immediately while the paint is still wet. If it has already dried, it is best to moisten the stain again and treat it with window cleaner, hair spray or brush cleaner on a sponge/cloth and wash it out again. We have also been successful with special stain remover against ballpoint pen, felt-tip pen and ink stains!
