How to erase scratches in wood floors and furniture with a walnut:
Let me start by saying that the example floor you are about to see is not in the best condition. I decided a year or two ago to remove the hideous blue stained wall-to-wall carpet from the house, and I love the results. Under the blue crusty monstrosity, there were lovely honey-colored wood floors. The wood was infinitely better than the carpet. But—the floor itself was fairly scratched and stained. This walnut trick works better with new scratches; not so much with scratches that have existed underneath wall-to-wall carpeting for 30 or 40 years.
