While there are no guarantees that cherry juice will come out of your fabric, you can increase the odds for success by treating the stain and soaking the fabric. If pretreatment and the first soaking do not work, you can try soaking the fabric briefly in a stronger solution.
Place the fabric on a flat surface. Make sure the stained part of the fabric is placed in a single layer on the surface. The cherry juice could bleed onto the bottom layer if the fabric is double-layered. Place at least four paper towels under the stain to keep the color from spreading.
Cover the whole stain generously with liquid laundry detergent. Brush the detergent into the stained fabric fibers using a toothbrush or scrub brush. Work from the outer edge of the stain and toward the stain's center.
Place the fabric in a washbasin and pour a scoop of all-purpose powdered bleach on the stained area. Fill the washbasin with water and agitate the fabric with your hand until the powdered bleach dissolves. Soak the stained fabric overnight.
Drain the powdered bleach solution and run the fabric through the washing machine on a cold-water setting.
Check if the stain is gone. If it is, dry the fabric as you normally would. If the fabric is colored and the stain is still there, pour lemon juice over the stain and scrub it gently with a toothbrush using an inward motion.
Use white vinegar if the lemon juice does not dissolve the stain. Rub the vinegar inward from the outer edge of the stain using a soft cloth. This is the last resort if the fabric is colored.
For fabric that is white or colorfast, mix one cup of liquid bleach in per gallon of water. Soak the fabric in the solution for up to 15 minutes. If the stain is still there, it can't be removed. Continued soaking will only create more damage to the fabric.
