What stain remover removes coffee stains?

Vinegar and Baking Soda:

1. Blot up the stain immediately. Don't rub it, as this can spread the stain and make it more difficult to remove.

2. Apply a paste made of equal parts white vinegar and baking soda. Make sure to cover the entire stain and let it sit for 5-10 minutes.

3. Blot the stain again. Use a clean, damp cloth to blot the stain until it disappears.

4. Rinse the area thoroughly with water. Make sure to rinse all of the vinegar and baking soda residue away.

5. Repeat steps 2-4 if necessary. If the stain is still visible, repeat steps 2-4 until the stain is completely removed.
