Carbon Lab Nubuck Suede Cleaner. The block to remove even the smallest spots from your sneakers. When cleaning sneakers, always start without water and wet cleaning products. The Nubuck Suede Cleaner has been specially developed in the Collonil lab to clean stains in suede and nubuck without moisture. Note: not intended for older dehydrated nubuck on Nike Air Max 1s. The cleaning block is part of the Carbon Lab Dry Cleaning process and has two useful sides: a foam side and crepe side. The foam side is meant to get the hint of suede back, for example after you’ve treated the sneakers with Carbon Lab Cleaning Solution. The crepe side is sticky and therefore easily loosens dirt. You can simply remove stains by rubbing the block in a focused way. 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.
