Scrub away stuck on food and... microplastics (Jeremy) Our loofie is an exceptional scrubber loved for its longevity, durability, and lack of unpleasant odors unlike traditional sponges. Our plastic-free loofie scrubbers are a combination of the gentle scrubbing power of the fibrous loofah plant and the spongy cellulose-cotton dishcloth. They're even sewn together using cotton thread (rather than the all-too-commonly used polyester thread), making them reusable and biodegradable with absolutely no plastic.
