How do you go away stain?

To remove a stain, first identify the type of stain and fabric. Blot the stain gently with a clean cloth to absorb excess liquid, avoiding rubbing which can spread it. Apply a suitable stain remover or a mixture of water and mild soap, letting it sit for a few minutes before rinsing. Wash the item as per care instructions, and check if the stain is gone before drying, as heat can set stains.
