## Why It Works
Leather is protein — specifically collagen fibers — and egg white is also largely protein (albumin). The egg white's proteins have a natural affinity for the leather surface, filling microscopic surface irregularities and creating a thin, smooth film as they dry. This film reflects light evenly, which is what produces the shine. The mild acidity of egg white also helps remove surface oxidation that dulls leather. It's a conditioning treatment and a shine treatment in one application.
## How to Do It
1. Clean the leather first with a damp cloth to remove dirt and dust. Let dry.
2. Separate one egg white into a bowl.
3. Beat with a fork until frothy — slightly aerated egg white spreads more evenly.
4. Dip a soft, clean cloth into the egg white. Apply in small circular motions to the leather surface. Work in sections.
5. Let the thin layer dry partially — about 3 to 5 minutes. Don't let it dry completely or it becomes difficult to buff.
6. Buff vigorously with a clean, dry cloth until the haze clears and the leather shines.
7. Apply a coat of proper leather conditioner or shoe polish afterward to seal the surface.
## Pro Tips
- This technique works on smooth, finished leather: dress shoes, leather bags, jacket panels.
- Do not use on suede, nubuck, patent leather, or any leather that cannot be dampened.
- The shine is real but temporary — a few days on a bag, a week on shoes you're actively wearing. Follow up with a wax-based shoe polish for lasting results.
## When to Use This
Emergency shoe shine before an event, or as a periodic conditioning treatment for leather goods that are looking dull and neglected. Works well on vintage leather that can't handle harsh commercial products.
