This oil, pressed purely from Japanese Tsubaki seeds, feels gentle and safe to handle. Its texture is light yet slightly viscous, allowing it to seep into small cracks and crevices, whether on tools, knives, or wooden surfaces. It is clear and pristine, without any cloudiness or sediments.I have used similar oils before, and this one is smooth and fluid, spreading easily while holding just enough body to cling to surfaces. It does not feel watery, nor heavy or greasy, and the scent is almost imperceptible, with just a faint nutty sweetness.I favour it over harsh rust removers, which often rely on strong acids or abrasive chemicals. Tsubaki oil is gentle yet effective, softening rust without aggressive scrubbing. Once applied, it stays liquid long enough to protect edges and moving parts, and being non-toxic, it is entirely safe for kitchen knives or tools that touch food.Top-quality Tsubaki oil carries natural antioxidants, which help slow oxidation. Applied to metal, it penetrates tiny scratches and softens light rust, making it easy to wipe or brush away. Afterward, it leaves a thin, protective layer without any sticky residue.Camellia oil generally keeps for 2 to 3 years unopened, and around 6 to 12 months once opened. Since this comes in a transparent plastic bottle, sunlight or bright indoor light can speed up oxidation, causing it to lose its rust-prevention properties or go rancid more quickly. For this reason, I store the bottle in a cool, dark, dry spot, usually a cupboard or toolbox. I do wish it came in a dark glass dropper or an opaque, airtight container, which would make long-term storage even easier.Nevertheless, this is a natural, multi-purpose solution that is gentle, protective, and versatile, perfect for those who prefer to care for metal without harsh chemicals, while leaving a layer of long-term protection.
