Dawn Dishwashing Liquid is a powerful cleaning agent that can remove grease from clothing. When using Dawn to remove grease stains, it is important to treat the stain as soon as possible after it occurs. The sooner you treat the stain, the easier it will be to remove. To remove a fresh grease stain, simply apply Dawn directly to the stain and rub gently with a clean cloth until the stain is removed. You may need to repeat this process for older or more stubborn stains.
