To clean the SF1 driver, use a soft cloth and warm water to wipe off any dirt or grass stains from the clubhead and shaft. You can also use a mild soap or detergent if needed. Avoid using any abrasive or harsh chemicals. Clean the grooves and face with a soft brush or tee. Dry the club thoroughly before storing it in a cool, dry place, and use a headcover to protect it from dust and scratches.
