Mineral Oil: The Ultimate Knife Care Essential

Mineral oil is a colorless, odorless liquid that is often used as a lubricant. It is also used as a rust preventative and as a waterproofing agent. Mineral oil is safe to use on knives, and it will help to keep them sharp and free of rust. To apply mineral oil to a knife, simply wipe it on with a clean cloth. You can also use a cotton swab to apply mineral oil to hard-to-reach areas.
