Mustard stains on an outdoor sofa can be stubborn and unsightly, but with the right approach, you can prevent and tackle them effectively. Here’s how:

1. Act Quickly: Blot the stain immediately with a clean cloth to absorb excess mustard before it sets. Avoid rubbing, as this can spread the stain.

2. Use a Mild Detergent: Mix warm water with a few drops of dish soap. Gently dab the solution onto the stain using a soft cloth or sponge, then rinse with cold water.

3. Try Baking Soda Paste: For tougher stains, make a paste of baking soda and water. Apply it to the stain, let it sit for 15 minutes, then wipe clean.

4. Protect Your Sofa: Apply a fabric protector spray designed for outdoor furniture to create a barrier against future stains.

5. Regular Maintenance: Clean your sofa regularly to prevent dirt and spills from becoming permanent stains.

By following these steps, you can keep your outdoor sofa looking fresh and stain-free, even after messy outdoor meals.
