Using this vintage wooden churn is quite simple. First, pour your cream into the churn. Then, use a proper churning tool to move the cream back and forth inside the churn. Keep doing this until the cream turns into butter. As for the maintenance, after each use, make sure to clean the churn thoroughly with warm water and a mild detergent. Don't soak it for too long as wood can absorb water and may get damaged. Dry it completely with a soft cloth. Also, store it in a cool and dry place to prevent any warping or mold growth. Be gentle when handling it because it's an old piece and might be a bit fragile.
