Razor blades are a quick way to get rid of unwanted body hair, but they must be properly cared for in order to prevent rusting. Rust forms on razor blades when water sits on the metal, causing it to oxidize. Once a razor blade rusts, it quickly becomes dull, which can result in nicks and cuts during shaving. Keep your razor blade from rusting by taking simple measures after each use.
Rinse your blade after each use to remove dead skin cells, hair and shaving cream. Dry the blade well with a rag to remove any moisture.
Store your razor blade outside of the bathroom. Leaving your razor in the shower is a quick way for rust to form, but even being in the bathroom away from the shower can cause rusting due to the excessive humidity in the room. Instead, store the razor somewhere else, such as in a drawer or on a shelf outside of the bathroom and away from moisture.
Apply camellia, baby or mineral oil to the blades with a rag after each use to further prevent rusting. Make sure the blades are completely dry before applying the oil. Oiling the blades helps to prevent oxidization of the metal, which leads to rusting.
