Made from white teakwood and stiff agave fiber bristles, this dish brush replaces plastic handled dish brushes at your kitchen sink. Each brush head can be used for 1-6 months. Hang to dry or place in a dry location to prevent your brush from swelling or cracking. White teakwood is naturally antibacterial, but if you find your brush is not staying dry, dip in vinegar occasionally to help kill bacteria. To replace the brush head the first time, you may need to use pliers to loosen the wires. After that, strong fingers should be sufficient. Squeeze the wires together, loosen the metal grip and pop off the brush head.
