Act fast, using a spoon or knife to scrape off as much of the fruit (juice) as possible from the surface of the fabric.
Soak the stain in cold water. If possible and the garment is washable, flush the stain through from the inside out as this will push the stain out of the fibres. Make sure it is cold water, hot water might set the stain. Put some stain remover or liquid detergent on the stain and gently work it into the stain in circular motions for a while with your finger or a small brush. For colored garments, make sure to use color safe, non-chlorine/bleach-free stain remover. If you don't have liquid wash detergent or stain remover, simply use dish washing liquid. If the stain is still visible, repeat this step.
In worst case, use a mild bleach on the stubborn stain before next step. For colored garments, make sure to use color safe, non-chlorine bleach and check their colorfastness to bleach first. For wool products, skip this step.
When you can’t see the stain any more, dry the garment or wash it as normal in the machine.
