Pack books flat and not standing on end to protect their spines. Books are very heavy, so pack them in small boxes and do not mix them in boxes with other, more fragile, items.
Store mattresses and box springs on long edges. Wrap them with plastic for protection from dust and moisture. Elevate off the floor by using pallets or 30 cm pieces of plywood.
Disassemble tables, bed frames, etc. to save space. Wrap and label all pieces for an easier task when you have to reassemble them later. If possible store sofas on end and stack chairs seat to seat. When stacking furniture use carton pads in between the items to avoid scratching.
Store mirrors and pictures inside similarly sized knock down boxes to protect them from scratches and dust. Store them on end and not flat.
Group similar items together and use bubble wrap or unprinted paper to wrap breakables. The ink from printed newspaper may smudge and get onto your items. When wrapping smaller breakable items, tape it after you wrap it. This will avoid mistaking them for excess paper to fill the box. Stack boxes containing breakables on the top layer to avoid breakages.
Have blankets, draperies and clothing articles cleaned, and then pack them on hangers in wardrobe boxes to retain their original shapes.
To prevent rusting, rub a small amount of machine oil on metal tools, bicycles, and equipment. Drain and clean all debris from all equipment before you store them. Put all tools and hardware in bags and mark the bags accordingly.
Clean and dry all appliances prior to self storage. Store all appliances upright with doors ajar to allow ventilation and to prevent mildew. You may want to use the inside of appliances and drawers to store smaller items to save space, but DO NOT store food items as they will invite pests.
