Dab a cloth with wood cleaner and wipe down the wooden surface thoroughly. Dry the surface thoroughly with the other side of the cloth.
Plug your iron into a power outlet near the wooden surface and allow it to heat up.
Place another cloth over the area of the surface with the stain. Make sure the cloth is large enough to cover the entire stain.
Place the iron over the cloth and set it to high heat and steam.
Press firmly down on the iron and work the cloth over the stained area in circular motions. The heat and steam, filtered through the cloth, will begin removing the stain.
Check the stain to see if it is gone and repeat the steps as necessary until it is.
Remove the iron and cloth and dry the wooden surface area thoroughly to remove any moisture.
