It's gentle enough to clean fruits and vegetables, but tough enough to clean stubborn pots, pans, and soiled dishware. The Natural Loofah Kitchen Scrubber is made from 100% natural loofah fibres, and is safe to use on wood, glass, porcelain, stainless steel, copper, seasoned cast iron, appliances, counter tops, and delicate non-stick surfaces. To clean your Loofah, just rinse, squeeze, and hang to air dry. The long lasting scrubber is coloured with 100% natural vegetable dyes, and is non-toxic and biodegradable. Partial proceeds from this product are donated back to India, where the loofah gourds are grown.
