Tough stains like grease, wine, or ink can ruin clothes, but with the right approach, they can be removed. Pre-treat the stain with a detergent or stain remover before washing. For grease stains, dish soap works wonders, as it breaks down oils.
For wine or coffee stains, a combination of baking soda and vinegar is effective. Ink stains can be removed using rubbing alcohol. Always remember to treat the stain as soon as possible, and avoid using heat, which can set the stain permanently.
With these techniques, even the toughest stains can be managed.
