Surface dirt on all Colorado Case, Small Dog & Cavallaro products can be removed with a damp towel. A gentle fabric cleaner can be used if needed. For extremely dirty case covers, they can be washed by hand or in a gentle washing machine cycle. It is important to only use cold water and to air dry. Heat may cause your cover to shrink. Soft cases should never be machine washed or dry cleaned. The Cordura shell of rigid cases can be removed and cleaned like a case cover if necessary.
