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.
This can also be done chemically with store bought muriatic acid. Then run it through a neutralizing bath after. Not sure if either way is better. Just depends on what you have and if you like hazardous chem or not 😉
