More and more clients required to use
anti-rust vegetable oil to protect
metal castings. Why? It is mainly because vegetable oil is
free of pollution and toxic substances. So, they are suitable to be

Vegetable oil is also called as rust-proof veggie oil, which a kind
of anti-corrosive oil with main content of vegetable oil such as
wood oil or rape seed oil. This oil can be dry quickly, and form a
transparent thin oil film on the surface of metal castings, and they
could protect castings from rust very well.
Of course, the best advantage of veggie oil is no pollution and
toxic. Moreover, they have two more good characters:
1. They could become a solid film on the surface of castings, which
means the dry oil is not easy to dirty hands.
2. They are transparent, so you could see the
casting defects and
repairing positions on the surfaces.
Vegetable oil is different with normal oil for rust protection. The
normal anti-rust oil is applied for the machining surfaces, which
means they could be the lubricating oil too, but they are difficult
to dry, even after drying, they are still a little sticky, so they
are suitable for protect machining surfaces, but not suitable for
protect rough surfaces of metal castings.
