How to Remove Poster Paint
- 1). Apply some full-strength liquid laundry detergent to the stained area and rinse the fabric. If this doesn't completely remove the stain, go on to Step 2.
- 2). Mix some all-fabric powdered bleach with water to create a diluted solution. Pour this solution into a container and soak the garment in it. If this doesn’t remove the stain, move on to Step 3 to try another method.
- 3). Create a solution of liquid chlorine bleach and water. You can use this to soak the garment if it is white or light-colored, but bleaching can change the color of the fabric. You may want to test the bleach solution on a hidden area of the garment. Soak the garment in the diluted solution for 15 minutes. Proceed to Step 4 if bleaching is not possible or didn’t remove the stain.
- 4). Apply a color-removing product. Make sure to follow the directions on the label of the product to treat the stain. This will take the poster paint out, but it will also remove all of the color from your garment. This step is not recommended for colored fabrics. After applying the product, wash and dry your garment.
