If the ink-return seal is added with atomic ink, you need to follow the following steps:

1. Tools that need to be prepared: ink-return seal, atomic ink, paper towel or cotton swab.

2. Press the seal about 3mm to push out the built-in printing platform.

3. Drop an appropriate amount of atomic printing ink on the surface of the printing platform.

4. Use the same method to press the stamp again, about 3mm, and put the printing platform back.

5. If the wrong oil is added, you can use a lot of water to clean it, and you can also add some mild hand sanitizer and press gently.

6. After cleaning, blot dry with paper towels. Be careful not to damage the printing platform surface.

The above steps are for reference only. You can judge whether you need to find a professional to handle it based on the actual situation.
