Using this vintage butter churn is a breeze. First, pour your cream into the churn. Then, start the churning process by moving the handle back and forth. Keep at it until the cream turns into butter. As for care, make sure to clean it right after use. Wash it with mild soap and warm water, then dry it thoroughly to prevent any mold or damage. Also, store it in a cool, dry place. Avoid using it for any other liquids apart from cream to maintain its original function.
