1. Clean Your Mattress

Putting a dirty mattress in a storage unit can result in mold, fungus or at least a dirty mattress coming out of storage. To avoid this problem, consider the following steps for a clean, ready-to-use mattress upon retrieval from storage. 
  • Vacuum the mattress thoroughly.
  • Apply upholstery cleaner or baking soda.
  • Place mattress outside to air out and dry.
  • Use a covered moving truck to transport to the storage facility.
Whichever cleaning method you choose, remember to avoid soaking the mattress to ensure it is fully dry before storing. This will ensure you avoid any mold or mildew and any other damages to your mattress.

2. Wrap It in a Mattress Storage Bag

If you have your mattress in a garage or storage unit, keep it covered to protect against not only dirt and dust but also moisture. Mattress Storage bags are available at many hardware and furniture warehouses. If you are using plastic, be sure to thoroughly clean and dry the mattress before wrapping it. Otherwise, you could be sealing in moisture instead of keeping it out.

3. Store It Flat and Free of Items

If you have the space to store the mattress flat, manufactures recommend this for keeping it in good shape. It may be more convenient to store your mattress standing, but when it's stored upright, the coils and springs can shift and cause the mattress fabric to sag. Lay a tarp down on the floor before placing the mattress on top. However, never store items on top of the mattress. It is not a steady surface and the objects can damage the springs and cause cuts or permanent dents in the cushioning. If you have large boxes or flat furniture where the mattress will be stored, you may lay the mattress on top. 

4. Freshen It Up Before Use

If, despite your efforts, the mattress comes out of storage smelling musty and dirty, here's how to freshen it up:
  • Sprinkle baking soda on each side to absorb the smell.
  • After 10 minutes, vacuum the entire mattress.
  • Spray the mattress with a natural deodorizing spray and allow it to air-dry completely.
  • To ensure it has time to air out, remove mattress from storage at least 24 hours before you need to use it.

There is no reason to toss a perfectly good mattress out to the curb.
