How can I effectively remove screws from wood?

To effectively remove screws from wood, use a screwdriver that fits the screw head properly. Apply firm pressure while turning the screwdriver counterclockwise to loosen the screw. If the screw is stuck, try using a lubricant like WD-40 or applying heat to the screw with a hairdryer. If the screw head is stripped, use a screw extractor tool to grip and remove the screw.
