To remove rust by electrolysis, follow these steps:
1. **Materials Needed**:
- A container (plastic or glass)
- Water
- Washing soda (sodium carbonate)
- A power source (battery charger or DC power supply)
- An anode (scrap metal, like rebar)
- The rusted item (cathode)
2. **Setup**:
- Fill the container with water and add washing soda (about 1 tablespoon per gallon).
- Connect the anode to the positive terminal of the power source and place it in the solution.
- Connect the rusted item to the negative terminal and submerge it in the solution.
3. **Electrolysis Process**:
- Turn on the power source. Bubbles will form, indicating the process is working.
- Let it run for several hours, checking periodically.
4. **Finish Up**:
- Once the rust is removed, turn off the power, remove the item, and rinse it with water.
- Dry and apply a protective coating to prevent future rust.
Always take safety precautions when working with electricity and chemicals.
