Carbon Lab Microfiber Cloth. The cloth to clean your sneakers without unnecessary discolouration. Just a wipe? Certainly not! This microfiber cloth has been developed in the Collonil lab to optimally clean sneakers. They absorb dirt better than you expect and can be washed up to 70 degrees. This cloth is excellent to use in combination with, for example, the Midsole Cleaner and Cleaning Solution. Also when you use the other Carbon Lab care products you use the special cloth for after-treatment of your sneakers. 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.
