How can I effectively remove a butter stain from clothing or fabric?

To effectively remove a butter stain from clothing or fabric, first scrape off any excess butter with a dull knife or spoon. Then, apply a pre-treatment stain remover or liquid laundry detergent directly to the stain and let it sit for a few minutes. Wash the garment in the hottest water temperature safe for the fabric, and check the stain before drying. If the stain persists, repeat the process or consider seeking professional cleaning help.
