"Oil conditioning" gives copper tea utensils that have been loved for years—or those being stored for long periods—a rich, soft luster while reinforcing their protective film. We explain the safe care procedure using natural vegetable oils, a method used since ancient times for Japanese swords and traditional metalwork.
1. Choosing the right oil: Non-drying or semi-drying oils
- Pure Camellia Oil (Recommended): The premier protective oil; it resists oxidation and has almost no odor. It spreads thinly over metal surfaces to provide an elegant sheen.
- Walnut Oil: A natural oil long cherished for polishing woodwork and metalware, known for its smooth, non-sticky texture.
- Note: Do not use edible salad oil or olive oil: Over time, these will oxidize, causing unpleasant odors and stickiness.
2. The correct oil care procedure (the golden rule is "a very thin layer")
- Clean and dry the vessel: Completely remove all moisture and dust.
- Apply just one drop to a cloth: Do not drip oil directly onto the vessel; instead, apply one or two rice-grain-sized drops to a soft cotton cloth.
- Apply a very thin layer over the entire surface: Rub the oil from the cloth thinly and evenly across the entire vessel.
- Wipe completely dry with a clean, dry cloth: Carefully buff the surface until it feels smooth to ensure no excess oil remains (if oil is left behind, it will attract dust).
