To protect the oxidized metal from corrosion traditionally a mixture composed of:
- Lamp oil used for oil lamps
- Boiled linseed oil used in carpentry to protect wood
Linseed oil dissolves perfectly in the oil which penetrates into the pores of the oxide, dragging the linseed oil with it. Over time the petroleum dries and cooked linseed oil forms a rubbery substance that preserves the metal.
Anti-corrosion protection=Lamp oil + Linseed oil between 30% and 50%
The protective mixture is easy to apply with a brush and will be absorbed by the metal. Let the treated piece air dry and repeat the application several times.
