Coat blades with mineral oil after each use

Applying a thin film of oil to razor blades after drying creates a hydrophobic barrier that blocks moisture and oxygen from reaching the steel surface, preventing the oxidation that dulls edges between shaves.

Steps

1. Rinse and dry the razor thoroughly after shaving.
2. Apply one small drop of mineral oil or baby oil onto the blade cartridge.
3. Spread evenly across all blade surfaces using a fingertip or cotton swab, ensuring full coverage.
4. Rinse off the oil with warm water before your next shave.

Why It Works

Mineral oil is non-reactive and does not evaporate at room temperature, so it stays on the blade surface indefinitely between shaves. It fills the micro-grooves where water would otherwise collect and initiate corrosion. Combined with proper drying, an oil coating can extend blade life to 30+ shaves -- roughly 3-4x longer than untreated blades stored in a humid bathroom.

Tips

• Mineral oil is the best choice because it does not go rancid, has no scent residue, and costs about $3-5 for a bottle that lasts months
• Baby oil is mineral oil with added fragrance -- works equally well
• Avoid vegetable or olive oil for long-term use as they oxidize and develop off-smells within a week
• Most effective when combined with dry storage (Solution 1003) for maximum blade lifespan
