When initially washing a new canvas bag, soak it in salt water to prevent fading. Soak the bag in water with salt for about 20 minutes, then rinse in cold water. This can effectively reduce fading.
When choosing detergents, avoid products containing bleach or fluorescent agents, as they can damage the canvas material and color. While a moderate amount of detergent can effectively remove stains, be careful to limit the amount used to avoid waste and increase cleaning difficulty.
After washing, avoid exposing canvas bags to direct sunlight. It's best to air dry them in a cool, well-ventilated area. Turn the bag inside out when drying to prevent fading and mold growth.
