As a general rule of thumb for a child's safety, disinfectants (alcohol or bleach based) should not be applied directly to any wooden early childhood toys or game pieces. Why? Wood is a naturally organic material and disinfectants damage the water based protective coatings applied to protect the stains and/or colors beneath. To clean wooden toys, we recommend using a lightly damp cloth; the cloth can be simply dampened with warm water. If you wish to infuse any cleaning agent we recommend 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 the toy we strongly encourage to 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.
