“The story is, Australian sheep farmers noticed that steel things that sheep often rubbed against did not rust. Sheep’s wool is thick with lanolin, which is removed in processing the wool. Soap makers use it, it is also used in cosmetics.One pound of anhydrous lanolin from eBay costs about $16. I mix it about 10:1 with light oil and apply with a brush or cloth. I also mix it with WD40 in a trigger spray. A pound goes a long way.
Since starting this about 10 years ago, rust is a thing of the past – except where I failed to apply this mixture. It has been 100% effective.”
And if you have an item that already has rust, there’s Evapo-Rust.
