Using your VitaJuwel cleaning brush is a breeze. First, wet the brush under running water and add a bit of mild dish soap. Then, gently scrub the inside of your VitaJuwel glass vessel with the curved head, reaching all the corners easily. After cleaning, rinse the brush thoroughly to remove any soap residue. As for maintenance, let the brush dry completely in an upright position to prevent the bristles from getting damaged. Avoid using harsh chemicals on the brush as it's made of natural materials. Also, store it in a dry place. With proper care, this brush will serve you well for a long time.
