Are Penetrating Oil and Rust Remover the Same?

[McHenry]

Penetrating oil and rust remover are not the same. Penetrating Oil: Penetrating oil, also known as anti-rust lubricant, is primarily composed of petroleum solvents, rust inhibitors, and lubricants. It is a multi-purpose metal maintenance product with functions such as rust prevention, rust loosening, moisture removal, lubrication, cleaning, and electrical conductivity. Rust Remover: Rust remover is an ideal lubricating coolant suitable for tapping threads on stainless steel and aluminum surfaces. Additionally, it can effectively clean and dry electronic equipment, improve conductivity, and is widely used in various industries such as manufacturing, repair, energy, and power. Differences: Penetrating oil mainly serves a lubricating function, while rust remover primarily acts to loosen rusted fasteners. The materials, methods, functions, and effects of the two differ, although both can form a protective film and have the effect of preventing metal rust.
