We recommend gently hosing your boots off after use and handwashing in cold water with minimal detergent if necessary. Brush off dried mud before washing to help minimize stains. Many customers have had success with scotch guarding their boots to prevent stains, allow them to go longer between washes, and improve the longevity of airbrush color.Machine washing and power washing voids the warranty on most boot brands, including Iconoclast, and The Glamorous Cowgirl LLC is not liable for any damage to your boots or straps. Power washing will destroy the straps and leave obvious lines in airbrushed products.
