If you collect vintage Fisher Price Little People, it's important that you know how to prepare, pack and store the sets so that they remain in the same good condition that they are in now, for years to come. When the time comes to store the A-Frame house set made in 1974, there are a few extra things to do to protect it while it's being stored. Here's what you need to know.

Clean the Set

One mistake that people often make when cleaning the A-Frame house is that they spray it down with cleaner and then wipe it down. Never spray any liquids directly onto these houses. There are stickers inside and out that will absorb the moisture and become discolored and possibly even peel.

Instead, spray a clean cloth with a little bit of cleaner. You want the cloth to be only slightly damp so that you're removing the dirt, but not dampening the stickers.

Inside the kitchen, you'll have some detail work to do. If you don't do the work before you store the set, the dirt that remains on the plastic will cause it to become discolored. So, get yourself some cotton swabs, toothpicks and a cleaning cloth and get all of the nooks and crannies completely clean.

Wipe down the furniture, people and the car. Use a toothpick to get any dirt that is lodged around the necks and in the holes out.

Set everything out to dry for a day before you pack it up.

Pack the Set

To keep the set in pristine condition, each piece should be individually wrapped with tissue paper. You don't want them rubbing up against each other while they're boxed and transported.

The house will require a little work. You see the bell on the porch? This is one piece that oftentimes gets broken off when the house is packed up in a box. Get a small sheet of bubble wrap. Wrap the bell carefully. Now, cut a piece of cardboard to fit the end of the house so that nothing can rub up against the bell. This will not only protect the bell from breaking off, but also keep the bell from scratching up the plastic windows.

Wrap the house in some bubble wrap, tuck it in a box with a separate bag or box with the smaller pieces inside. Fill the voids in the box with tissue paper so it doesn't shift around.

Store the Set

In order to avoid the set from yellowing, you'll need to find a place that is cool and dry. Never store these sets in a space that gets hot and humid or cool and moist. A cool, dry area is required. If you don't have a space in your home that meets these requirements, consider leasing a small personal storage unit to store this set and any other sets you don't have room to display at this time.
