Carbon Lab Odor Cleaner. The sneaker decoder to make your sneakers smell fresh again. Odor Cleaner immediately removes dirty musty odors. We’ve all been there: working out too hard, a sneaker purchased from a smoker or a pair of sneakers that started to smell musty in the closet. Odor Cleaner kills bacteria that cause these odors and this immediately results in a fresh sneaker. Of course you can also use this cleaning product for other clothing and sports equipment. Why Collonil Carbon Lab? Because Outsole thinks it’s important that you go for quality and not for hype. Collonil has been the market leader in shoe care for years and thoroughly tests all its products on different sneakers. The ecological footprint is concerned as well: Carbon Lab is based on safe organic ingredients.
