To Care

To keep your Grimm’s wooden toys in beautiful condition, gently wipe them with a damp cloth as needed. Avoid using harsh cleaners or soaking the toys in water, as this can damage the wood and the natural, non-toxic stains. Allow the toys to air dry completely after cleaning.

Since the wood is untreated and free from harmful chemicals, it’s normal for it to show natural variations and develop a unique patina over time. For an extra layer of care, you may periodically rub the toys with a food-safe oil to maintain their finish and preserve the wood’s natural beauty. Keep the toys in a dry place and out of direct sunlight to prevent fading and warping.

By following these simple steps, you can help ensure that your Grimm’s toys remain a cherished part of playtime for years to come.
