- Fill a commercial liquid tank with two parts of ammonia solution and three parts distilled water.
- Spray the interior surface of the sulfuric acid tank.
- Let the ammonia solution soak for two hours. The ammonia solution neutralizes the pH of the sulfuric acid.
- Test the pH of the sulfuric acid tank. Wipe a piece of litmus paper on the side of the tank. Litmus paper turns blue when contacted with acid, and turns red when contacted with a base.
- Repeat Step 2 and 3 until the litmus paper does not react.
- Drain the excess solution from the sulfuric acid tank. Leave the tank open to dry.
