Do you know what to do during a chimney fire? Call the fire department and exit the house - just like any other house fire. Many people choose not to do this, but if the fire does spread, don't you want the firefighters there already?
Most dedicated wood lovers insist that the best finish for a wood floor is a floor-formulated tung oil. Derived from the nut of the tung tree, tung oil penetrates the wood and bonds with the surface fibers. More giving than a synthetic finish, a tung-oiled floor will evolve with wear rather than cracking or chipping. Originally developed as as ship sealant, tung oil naturally provides excellent protection from spills, water, traffic, and dirt. Cleanup is simple, with a little clear vinegar in water or an oil soap mixed with water.
