Dear all,
As a lubricant engineer / specialist I can tell the following about anti rust using oils. There are different types of oil. There are mineral oils (often paraffinic based), vegetable oils (e.g. palmseed oil) or animal oils (e.g. fish oil). All these oils do not prevent rusting. They only give a simpel layer on the metal surface so oxygen and / or water are kept away. Animal and / or vegetable oils tend to oxidise much easyer than mineral oils and are therefor less suitable as anti rust oils. In the long run a straight oil (without additives) is a poor anti rust agent. It is therefor that you need to oil a keris regularly to keep te rust away. You could use an oil with anti rust additives in it. Do not use e.g. WD-40 since it does not contain any anti rust additives and is simple a mixture of mineral oil with solvent in a spraycan. I always use the multi spray of OKS (German brand) on my krises. This is a mineral oil with a mild anti rust additive (in a spraycan). It gives a far better rust protection and does not stain the metal surface. (This works perfect for me. If you try it it is for your own risk
).
Cheers,
Bart.
