Below are instructions on how you can safely wash a backpack: 1. Check the label - Before you wash your bags, check the care label to see if it is safe for machine washing or requires hand washing or spot cleaning. 2. Empty the backpack - Ensure the back is empty. You should remove all of the contents in the bag. Check all of the pockets. Also, double-check if there are no electronic devices, such as lights, within the bag to avoid it from getting ruined. 3. Fill the sink or bathtub - Fill the sink or bathtub with warm water and gentle soap, such as a mild detergent or specialized backpack cleaner. Avoid using harsh chemicals like bleach, as they can damage the material. 4. Scrub the backpack - You can gently scrub the backpack with a soft brush or cloth, paying extra attention to any dirty or stained areas. 5. Rinse thoroughly - Rinse the backpack thoroughly with warm water to remove all soap and dirt. 6. Hang to dry - Hang the backpack to air dry, either by using a clothesline or by propping it up with towels. You can also let it dry from the sun, but you have to double-check that once dry, you can put it back indoors to avoid too much heat or getting wet from the rain, as it may damage the fabric and may cause discoloration. Also, avoid using a dryer, as high heat can damage the backpack's material. 7. Store properly - Once the backpack is dry, store it in a cool and dry place. Avoid storing it in direct sunlight, as this can cause fading or damage to the material. These steps help clean your backpack thoroughly, prolong its lifespan, and keep its color and condition as long as possible. However, please take note that each backpack may require a different cleaning method, so make it a habit always to check the care label first.
