This is a replacement head for our kitchen brush made from beechwood with sisal fiber (agave plant) bristles. Great for everyday cleaning; gently and effectively scrubs dishware, glassware, pots and pans. Care Instructions: Hang to dry in between uses, on a dry towel or elevated to allow bristles to drain. Never leave submerged in water as it will wear on the wood causing it to crack or may cause the natural bristles to fall out. Heads last about 6 months, and handles last a couple of years. Wood is naturally antimicrobial, but if you need to clean your brushes, clean bristles with vinegar to kill bacteria. Brush Head Replacement: Pinch the wires together near the head of the brush and slide the small circular metal piece down to remove old brush head- you may need pliers the first time you change it. Slide a new brush head on and slide the metal piece back to its original position to hold it tight. Watch this how-to video. Refill heads have the option of coming coated with a natural plant varnish to reduce cracking or come naturally uncoated. Mother Earth Approved: Wooden with 100% sisal plant fiber bristles (agave plant). How to Dispose: Heads can be demoted to household cleaning then home composted. Sustainable Packaging and Shipping: Our products are shipped with zero plastic in recycled paper boxes or with kraft paper or compostable peanuts as padding.
