Each brush can be used for 1-3 months or longer depending on frequency of usage and proper storage. Make sure to not submerge or soak the wooden parts in water, the natural materials will absorb water and it will cause the brush to swell and crack. Hang to dry or place in a dry spot after using it.
If you find your brush is not staying dry, dip the bristles in vinegar occasionally to help kill bacteria. The Moso bamboo is naturally antibacterial but the vinegar will help too.
Continue using this brush until the bristles no longer work, then compost or bury in garden or dispose in a green waste bin. Stop using the brush and replace it if you see any mold growth.
Storage and Care:
To reduce cracking, keep the wood parts dry and do not soak or submerge them in water. You can oil your brushes to reduce the potential of cracking if you regularly submerge your dish brushes in water. Never store your brush in a wet spot between uses, it will cause the brush to absorb excess water and crack.
Place in a completely dry spot.
Hang to dry or place in a completely dry spot after using it. Do not rest the brush on top of your solid dish soap between dish washing sessions, the natural bristles will wick up excess water and cause the handle to crack.
Using with the DISH BLOCK®:
Keep in mind that when using the DISH BLOCK®, a soft sponge on most dishes is ideal for best longevity. If you use a hard bristle brush on all dishes, you will wear down the DISH BLOCK® faster than a sponge and might dig a hole in the middle of the soap.
End of life:
Once worn out, the bamboo and plant fiber parts can be composted or buried in the garden.
