6. Remember that more space costs more money. Anything you can do to keep your belongings compact is a good idea. Table legs come off and can be stored flat. Shelves come out of bookcases and the bookcases can be used to encase sofas. Recliners even come apart for better storage. Key idea: Any hardware you remove from a piece of furniture should be put in a plastic bag and taped to the object that it came from. It makes it easier to put the furniture back together once you need to use it again.
7. Sharp objects should not be stored in cardboard containers. Over time, these can cut through their containers. Use large plastic bins or trash cans to hold sharp items. Be sure to label the outside of the container to remind you to be careful when it comes time to unpack!
8. If you are storing items which contain liquids - such as humidifiers, chain saws, lawn mowers - be sure to drain them of their liquid. Not only might it be flammable, giving off damaging fumes even without ignition, it may also leak and cause mildew or water damage to your other belongings.
9. Cover cloth furniture (sofas, mattresses) with plastic. This can help protect them from dust or humidity effects. It is always recommended to store items made of cloth on a pallet up and off of the floor.
10. Wood furniture may dry out over time - be sure to treat them with a preservative before storing. If possible, protect them in plastic or cover them in cardboard to help protect their surfaces.
