Unfinished wood carvings are prone to fading and discoloration due to exposure to light, humidity, and environmental factors. To preserve their natural beauty, follow these effective methods:

1. Limit UV Exposure – Direct sunlight accelerates fading. Display carvings away from windows or use UV-filtering glass in display cases.

2. Apply a Protective Finish – Even if you prefer an unfinished look, a light coat of natural oils (like linseed or tung oil) can shield the wood without altering its appearance significantly.

3. Control Humidity Levels – Store carvings in a stable environment (40-60% humidity) to prevent warping and discoloration caused by moisture fluctuations.

4. Dust Regularly – Dust buildup can lead to uneven discoloration. Use a soft brush or microfiber cloth for gentle cleaning.

5. Avoid Harsh Chemicals – Cleaning with water or chemical sprays can cause stains. Instead, use a dry or slightly damp cloth.

6. Rotate Displayed Pieces – If displaying carvings, rotate them periodically to ensure even exposure to light and air.

By following these steps, you can maintain the natural charm of unfinished wood carvings for years to come.
