Did You Know?
1. Despite its name, muriatic acid is actually a diluted form of hydrochloric acid, containing roughly 31-35% hydrochloric acid concentration.
2. The term “muriatic” comes from the Latin word “muria,” which means brine or saltwater. This refers to the traditional source of hydrochloric acid, which was obtained by heating a mixture of brine and sulfuric acid.
3. Calcium carbonate, commonly found in many household products such as antacids and chalk, can neutralize muriatic acid. When calcium carbonate reacts with muriatic acid, it produces carbon dioxide gas, water, and calcium chloride.
4. When muriatic acid is mixed with ammonia, it can produce a toxic gas called chloramine. Chloramine can irritate the respiratory system and can be extremely harmful if inhaled in high concentrations.
5. Contrary to popular belief, vinegar is not an effective neutralizer for muriatic acid. Vinegar, which is an acid itself (acetic acid), does not significantly mitigate the corrosive effects of muriatic acid and might even cause further chemical reactions. It is best to use a specific neutralizing agent, such as baking soda or lime, to safely neutralize muriatic acid spills.
Baking Soda (Sodium Bicarbonate)
Baking soda, or sodium bicarbonate, is widely recognized for its ability to neutralize acids, including muriatic acid. When muriatic acid comes into contact with baking soda, a chemical reaction takes place, resulting in the production of carbon dioxide gas, water, and a salt. This reaction effectively neutralizes the acid and diminishes its corrosive nature.
To safely neutralize muriatic acid with baking soda, it is crucial to adhere to specific safety precautions. First and foremost, be sure to wear appropriate protective gear, such as gloves and goggles, to prevent accidental skin or eye contact with the acid. Additionally, perform the neutralization process in a well-ventilated area to avoid inhaling any potentially harmful fumes that may be released.
To initiate the neutralization process, carefully add small amounts of baking soda to the area where the muriatic acid has been spilled or applied. Use a non-reactive material, such as a plastic or wooden utensil, to gently stir the mixture, ensuring there are no undesired reactions. Keep adding baking soda until the acid has been completely neutralized, which is indicated by the absence of any fizzing or bubbling.

Lime (Calcium Oxide Or Calcium Hydroxide)
Lime, in the form of calcium oxide or calcium hydroxide, is another effective substance for neutralizing muriatic acid. It reacts with the acid to form a salt and water, thereby neutralizing its corrosive properties.
When using lime to neutralize muriatic acid, it is crucial to handle it with care due to its caustic nature. Similar to the procedure with baking soda, wear appropriate protective gear and work in a well-ventilated area.
To neutralize muriatic acid with lime, follow these steps:
- Sprinkle lime onto the affected area, ensuring it covers the entire spill or applied acid.
- Use a non-reactive material to gently mix the lime with the acid.
- As the lime reacts with the acid, it will generate heat and form a white precipitate.
- Stir the mixture until the acid is completely neutralized, indicated by the absence of any further chemical reaction.
Remember to exercise caution and prioritize safety when handling lime and muriatic acid.
Ammonia
Ammonia is an effective substance for neutralizing muriatic acid. However, it is important to note that using ammonia to neutralize strong acids like muriatic acid should be approached with caution due to the potential release of toxic fumes.
When working with ammonia, ensure that you are in a well-ventilated area and that you are wearing appropriate protective gear, including gloves and goggles. Begin by diluting the ammonia in water to reduce its concentration. Slowly add the diluted ammonia to the acid, working in small increments and cautiously observing the reaction. If the fumes become overwhelming or the reaction is vigorous, stop adding the ammonia and seek professional assistance.
- Ensure proper ventilation and wear protective gear (gloves and goggles).
- Dilute ammonia in water before use.
- Add diluted ammonia to the acid slowly and in small increments.
- Observe the reaction cautiously.
- Seek professional assistance if fumes become overwhelming or the reaction is vigorous.
Borax (Sodium Borate)
Borax, also known as sodium borate, is an effective substance for neutralizing muriatic acid. It acts as a mild alkali and helps counteract the corrosiveness of the acid.
To safely neutralize muriatic acid with borax, it is important to wear protective gear and work in a well-ventilated area. Start by adding small amounts of borax to the affected area, ensuring an even spread. Use a non-reactive material to mix the borax with the acid and observe any chemical reactions that may occur. Keep adding borax until the acid is fully neutralized, which is indicated by the absence of bubbling or fizzing.
Vinegar (Acetic Acid)
Vinegar, specifically acetic acid, can neutralize muriatic acid. Vinegar’s low pH helps to counteract the strong corrosiveness of muriatic acid.
When using vinegar to neutralize muriatic acid, safety precautions are crucial. Protective gear should be worn and work should be conducted in a well-ventilated area. Here’s how to proceed:
- Carefully pour vinegar onto the affected area, ensuring complete coverage.
- Use a non-reactive material to gently mix the vinegar with the acid. Watch for any chemical reactions.
- Repeat the process until there are no further reactions, indicating that the acid has been fully neutralized.
Remember to always follow safety guidelines and take necessary precautions when dealing with muriatic acid or any other acidic substance.
Other substances that can be used to neutralize muriatic acid include:
- Baking soda
- Lime
- Ammonia
- Borax
When in doubt, consult a professional to ensure safe handling and effective neutralization of muriatic acid.

Frequently Asked Questions
What is the best thing to neutralize muriatic acid?
In order to neutralize muriatic acid effectively, it is highly recommended to have a solution of baking soda and water readily accessible. While sprinkling baking soda or garden lime directly can provide results, a better approach is to combine ½ cup of baking soda with a quart of water in a sealed spray bottle. This prepared solution allows for a controlled and efficient neutralization process, ensuring the acid’s harmful effects are mitigated in a quick manner. Having this mixture easily accessible is crucial in maintaining a safe environment when working with muriatic acid.
Can you wash off muriatic acid with water?
Yes, you can effectively wash off muriatic acid with water. Once you have carefully applied the solution to the affected area, allowing it to sit for approximately 10 minutes, it is important to thoroughly rinse the area with water. Afterwards, to further neutralize any remaining acid, you can spray a solution of one-part ammonia to 10 parts water. Finally, ensure that the area is left to dry completely.
Does vinegar neutralize muriatic acid?
No, vinegar does not neutralize muriatic acid. Vinegar is itself an acid, consisting of acetic acid, and therefore cannot neutralize another acid. In fact, combining vinegar with muriatic acid may result in a potentially dangerous chemical reaction, as mixing acids can lead to the release of harmful gases. It is important to exercise caution and follow proper safety protocols when handling strong acids like muriatic acid.
Can milk neutralize muriatic acid?
While milk is commonly believed to have neutralizing properties for acid, it is not particularly effective in neutralizing muriatic acid. Muriatic acid, also known as hydrochloric acid, is a highly corrosive substance commonly used in industrial settings. Its extreme acidity, combined with the limited alkaline properties of milk, makes it insufficient for neutralizing muriatic acid. It is advisable to use more potent substances like specialized antacids or bases with higher alkaline content to safely neutralize muriatic acid, considering its corrosive nature and potentially harmful effects.
