My scrub brush cracked and discolored. Is this normal?

Yes, the wood of the scrub brush is untreated, so it is normal for it to get cracks and for there to be discoloration. We suggest not letting the brush soak in water for too long and let it dry with the bristles facing down. If it becomes so cracked that it's unusable or the bristles start falling out, please let us know and we'll replace it. Just email us at [e-mail] for assistance.
