Soy sauce stains on an outdoor sofa can be frustrating, but with the right techniques, you can prevent and remove them effectively. Here’s how:

1. Act Quickly: Blot the stain immediately with a clean cloth to absorb as much soy sauce as possible. Avoid rubbing, as it can spread the stain.

2. Use Mild Soap and Water: Mix a small amount of mild dish soap with warm water. Gently dab the stain with a sponge or soft cloth, then rinse with clean water.

3. Try Vinegar Solution: For stubborn stains, mix equal parts white vinegar and water. Apply to the stain, let it sit for a few minutes, then blot and rinse.

4. Apply Baking Soda Paste: Make a paste of baking soda and water, apply it to the stain, and let it dry before brushing it off. This helps lift the stain and neutralize odors.

5. Protect Your Sofa: Use a waterproof cover or fabric protector spray to shield your outdoor sofa from future spills.

By following these steps, you can keep your outdoor sofa looking clean and stain-free, even after accidental soy sauce spills.
