Can I use baking soda for this?

Yes! Pre-treat the stain by soaking a clean cloth in cold water and gently blotting the area with it. Then, make a paste by thoroughly mixing 1/2 cup of baking soda with ¼ cup of liquid dish soap and 4 cups of water. Using a clean cloth, dip it into the foamy solution and soak the affected area. Take another clean, dry cloth and blot the area to lift the stain from the upholstery. Alternate between saturating the area with the baking soda solution and blotting with the clean cloth until the stain is gone. Make sure you check the manufacturer’s label for specific care instructions first since some materials can't be treated with water.
