Prevent stains on your YSL handbag by applying a leather protectant spray. This will create a barrier against dirt, liquids, and other elements that could damage the leather. Regularly wipe your handbag with a soft cloth and store it in a dust bag when not in use. Avoid contact with sharp objects to prevent scratches.

To clean the interior fabric of your YSL handbag, gently remove any debris with a soft brush or lint roller. For tougher stains, use a damp cloth with mild soap and water. Avoid applying excessive moisture to prevent damage. Allow the interior fabric to air dry before using the handbag again.

When not using your YSL handbag, store it properly to maintain its shape and prevent damage. Stuff the bag with acid-free tissue paper or bubble wrap to retain its structure. Avoid storing it in areas with high humidity or extreme temperatures. Place it in a dust bag or a pillowcase to protect it from dust and light exposure.

Avoid overloading your YSL handbag with heavy items as it can strain the handles or shoulder straps. Distribute the weight evenly and avoid carrying unnecessary items. This will help maintain the shape and longevity of your handbag. If your handbag has a removable strap, consider removing it when not needed to prevent unnecessary stress on the hardware.
