How should I clean my bulletproof backpack?Updated a year ago

Our bulletproof backpacks are spot-clean only. 
DO NOT put your backpack in a washing machine or dryer as it may damage the bag.

To spot clean, you can follow these guidelines:
• Use mild soap (no fragrances or additives)
• Soft nylon bristled bush (ex: toothbrush)
• Use lukewarm water and brush sparingly
• Hang the bag in the shade or indoors, not in direct sunlight (UV light may degrade the fabric)
• Zippers may need occasional cleaning to remove fine sand, dust, and other particles. 
Be careful not to scrub as many zippers have water-resistant coatings that can rub off with force.
