BioThane is an extremely durable waterproof material that requires minimal maintenance to keep it looking great for a long time, however, there are a few things you can do to help prolong the life of your BioThane. Regular cleaning with a gentle detergent and an old toothbrush will easily take care of most spots and dirt. Tarnish from the solid brass hardware that may have transferred onto the BioThane may require some additional scrubbing remove, especially if intervals between cleaning are long. While BioThane is incredibly versatile, and repels MOST of the dirt and grime it comes across, please note that it is not completely stain proof in all circumstances.
