Summarize the following:
If your suitcase is made of fabric, you can protect it from further stains or damage by applying a fabric protector spray. Be sure to read the instructions thoroughly before using, as some materials, such as leather, can be damaged by fabric protectors. Metal hardware on your suitcase can be protected against scratches by using a metal lacquer or clear nail polish. Fabric suitcases that have had strong-smelling items spilled in them or that have been stored for a long period of time often develop unpleasant odors. Prevent this by first spraying with a liquid air freshener such as Febreze. Be careful not to spray air fresheners directly on leather! Before storing your suitcase, place a solid air freshener inside to prevent musty smells from developing. You can use commercial solid air fresheners, dryer sheets, unused bars of soap, cedar chips, or other similar items. Many suitcases become damaged through poor storage. When putting your suitcase away, check the area thoroughly for leaks, musty odors, and mildew, and store it elsewhere if necessary. Do not place heavy items on top of your suitcase, as this can warp it over time. If your suitcase is leather, aluminum, or hard plastic, wrap it in cloth to prevent scratches and scuffs while in storage.

Summary:
Apply a fabric protector spray. Treat metal hardware with lacquer. Spray with air freshener. Place a solid air freshener inside your suitcase. Choose a safe area to store your suitcase. Prevent damage to your suitcase while in storage.
