"Penetrant" means a lubricant designed and labeled primarily to loosen metal parts that have bonded together due to rusting, oxidation, or other causes. The term does not include multi-purpose lubricants that claim to have penetrating qualities, but are not labeled primarily to loosen bonded parts.
