Spot clean your wooden toys with a nontoxic cleaner or soap, diluted with water, or a solution of vinegar and water in a 1:1 or less ratio. White vinegar or Apple Cider vinegar work well for cleaning. Use a soft cloth or brush dampened with the cleaner, and never soak or immerse wood toys in water, as this can cause the wood to warp or crack and potentially weaken it. Be sure to dry the wood right away with an absorptive cloth and/or fresh air (avoiding too much sunlight).
