How to Remove Sulfuric Acid From Concrete

- Sodium bicarbonate (baking soda)

- Water

- Scrubbing brush

- Rubber gloves

- Safety glasses

Instructions:

1. Prepare the Cleaning Solution:

- Put on your rubber gloves and safety glasses to protect yourself.

- Mix equal parts of sodium bicarbonate and water to form a paste.

2. Apply the Paste:

- Apply the paste generously to the concrete surface affected by sulfuric acid.

- Spread it evenly, making sure to cover the entire area.

3. Let it Sit:

- Allow the paste to sit for at least 30 minutes. This gives time for the baking soda to neutralize the sulfuric acid.

4. Scrub the Surface:

- After 30 minutes, use the scrubbing brush to scrub the concrete surface vigorously.

- Apply some pressure to remove any remaining paste or stains.

5. Rinse Thoroughly:

- Use clean water to rinse the concrete surface thoroughly, ensuring all the paste has been removed.

6. Check and Repeat if Necessary:

- Inspect the concrete surface to see if the sulfuric acid stains have been removed. If not, repeat the process until the stains are eliminated.

7. Allow the Concrete to Dry:

- Let the concrete dry completely before walking on it or placing any objects on it.

Note:

- For tougher stains, you can also use a commercial concrete cleaner specifically designed to remove sulfuric acid stains. Follow the manufacturer's instructions for safe and effective use.

- If the sulfuric acid has caused significant damage to the concrete, it may be necessary to consult with a professional concrete restoration specialist for further assessment and repair.
