Loosen screws from wood without splitting the grain Using the best steam iron on the planet, Rowenta 

One of the most frustrating things to happen is for screws and nails that have been in wood for years split your wood creating holes and damages to your wood that could cost extra money to repair. Some people use wood glues and spackling to try and cover up the damage. But with nails and screws that's been in place for ages, you run the risk of creating a divot that can't be hidden. Well, here's a tip to help lessen the chance of those hair raising moments from happening.

Wood is a natural material. As with most natural material, it holds a certain level of water. When you cut a tree while it's moist, it cuts freely and doesn't do as much damage to the blade of the object used for cutting. Once the sap has dried out, using the same steps to cut wood will result in dulling the blade and marring the wood.

The same holds true with screws and nails in wood. Hammering or screwing them into soft moist wood is easy. But as the wood dries out, it draws to the metal. Trying to remove them tends to cause damage to both wood and metal object.

A tip to make the process easier and even use the same hole made by the screw is to fill your steam iron with water and place the temperature and steam at their highest temperature setting.

Hover the steam iron about one to two inches over the wood and screw. Letting the steam penetrate the wood. Try unscrewing or pulling out the nail with steady even pressure. Repeat as needed until metal object is free. If care is taken, you should be able to use  the same hole to secure the board back in place. using the steam iron prevents you from submerging the wood in excessive water; causing it to swell or discolor.
