- Fill with Vinegar: Pour white vinegar into the tank until it covers all rusted areas.
- Let it Sit: Allow the vinegar to sit for 24-48 hours, depending on the severity of the rust.
- Rinse and Repeat: After soaking, drain the vinegar and rinse the tank with water. You may need to repeat the process for stubborn rust.
- Neutralize and Dry: Finally, rinse the tank with a baking soda solution to neutralize any remaining acid and dry thoroughly.
