This sustainable swap helps you replace plastic pot scrubbers in the kitchen! This heavy duty scrub brush has a solid wood handle, with stiff plant fiber bristles. Designed for stuck on food and heavy stains, including for cast iron pots. Can be used on non-stick pans, just be more gentle with it. Each brush head can be used for 1-6 months. Do not leave any of the wood parts soaking in water, the wood will absorb water and it will cause the wood to swell and crack. Moso Bamboo. FSC certified by TÜV SÜD Czech, Prague.
