If you wish to disinfect the toy with a cleaning agent, use a small amount of either water and a mild dish soap or a water & vinegar essence mix. Both options work extremely well in destroying bacteria and cleaning wooden toys. After cleaning, wipe the toy dry with a clean cloth. Remember, Wood is a natural material that soaks in moisture. Do not ever submerse wooden toys in water or place in a dishwasher. Disinfectants (even organic baby wipes), should not be used as they can damage the water based protective coatings applied to protect the stains or paints beneath.
