How do I clean motorcycle tank?

To clean a motorcycle tank, start by draining any remaining fuel and removing the tank from the bike if possible. Use a mixture of warm water and a mild detergent to scrub the exterior gently with a soft cloth or sponge. For the interior, consider using a fuel tank cleaning solution or a mixture of vinegar and baking soda, then rinse thoroughly with water. Finally, ensure the tank is completely dry before reassembling and refilling it with fuel.
