Juice stains are marks left on surfaces or fabrics when juice spills occur. Common sources of juice stains include fruits like oranges, grapes, and berries. These stains can be challenging to remove due to the natural sugars and pigments found in the juice. To effectively treat juice stains, it is important to act quickly. Blotting the stain with a clean cloth and using cold water can help dilute the juice. For tougher stains, a mixture of detergent and water or specialized stain removers may be necessary to restore the affected area.
