Very excited to learn that you can fix scratches on wood floors and furniture with a walnut.
Yes — a walnut.
It’s the oil from the walnut meat that penetrates the wood. Coat a scratch with it and it will blend back in to the surrounding wood color.
As long as no one you’re preparing food for has a nut allergy you can also use them to correct any scratches in wooden bowls and kitchen utensils (and the oil is good for maintaining wooden cutting boards). Simply rub the scratched area with a shelled walnut to watch the scratch disappear, and then buff with a soft cloth. – How Stuff Works
I can see me now.
