This sustainable swap helps you replace steel wool or plastic pot scrubbers in the kitchen. Great for heavy duty jobs like stuck on food, heavy stains and cast iron pots. Can be used on non-stick pans, just be more gentle with it. Wooden handle with stiff plant fiber bristles (mixture of palm and sisal). 100% Biodegradable! Longevity: Can be used for up to 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.
