Yes, ammonia can kill mold on non-porous surfaces. It’s a strong chemical and should be used in a solution of equal parts water and ammonia. However, it’s ineffective on porous surfaces and can be harmful if mixed with bleach.
The Effectiveness of Ammonia Against Mold
Understanding Ammonia
Ammonia is a compound made of nitrogen and hydrogen with the formula NH3. It is a colorless gas with a distinct, pungent smell.
In many households, it is used as a powerful cleaning agent and can be found in a variety of cleaning products.
Its effectiveness in cleaning comes from its ability to break down dirt, grease, and other debris.
Disinfectant Qualities of Ammonia
Ammonia’s chemical properties make it a good disinfectant. It has a high pH level, making it alkaline, which helps in breaking down organic materials.
This property allows ammonia to disrupt the cellular structures of microorganisms like mold, ultimately leading to their death.
Ammonia’s Cellular Impact on Mold
When ammonia comes into contact with mold, it can penetrate the cell walls, causing the mold to lose its structure and die.
However, this is effective primarily on non-porous surfaces where the mold cannot deeply root itself. On porous surfaces, mold’s root structures, called hyphae, can remain unaffected.
Ammonia Versus Other Mold Killers
When compared to bleach, ammonia is sometimes seen as less effective because bleach can kill mold on both porous and non-porous surfaces. However, bleach does not always prevent future mold growth.
Other mold-killing solutions, such as vinegar or hydrogen peroxide, are less harsh and can be effective, especially for those sensitive to strong chemicals like ammonia or bleach.
When Ammonia Works Best?
Ammonia is most effective on non-porous surfaces such as glass, countertops, or tiles. It works well in removing mold from these surfaces as it can reach the mold on top without needing to penetrate a porous material.
Ammonia’s Mold Remediation Limitations
Ammonia’s effectiveness is limited when dealing with porous materials like wood or drywall.
In these cases, it cannot reach the root structures of the mold, which are essential to completely eradicate an infestation.
Additionally, ammonia does not prevent mold from returning, making it a less ideal solution for long-term mold control.
Safety Considerations When Using Ammonia to Kill Mold
The Hazards of Ammonia
Ammonia is classified as a hazardous substance. It can be corrosive and can cause irritation to the skin, eyes, and respiratory system.
In high concentrations, ammonia vapors can be highly toxic and potentially fatal if inhaled.
Health Risks of Ammonia Exposure
Exposure to ammonia can lead to a variety of health issues. Inhaling ammonia fumes can cause coughing, throat irritation, and in severe cases, respiratory distress.
Skin contact can result in burns, while eye contact can cause serious eye damage.
Handling Ammonia Safely
When using ammonia, always ensure that the space is well-ventilated. Open windows and use fans to circulate fresh air.
Never mix ammonia with bleach or other chemicals as this can create toxic gases.
Effective Ammonia Concentrations
For mold removal, a solution of 50% water and 50% ammonia is generally recommended. This concentration is strong enough to kill mold on non-porous surfaces without being overly corrosive.
Personal Protective Equipment (PPE)
When working with ammonia, wearing appropriate PPE is essential. This includes gloves, goggles, and a face mask or respirator. Protective clothing can also help prevent skin contact.
Ventilation During Ammonia Use
Always use ammonia in areas with plenty of air movement. This helps to disperse the fumes quickly and reduces the risk of inhaling toxic vapors.
If you cannot ventilate the area well, it is best to seek alternative mold removal methods.
Best Practices for Using Ammonia to Remove Mold
Step-by-Step Ammonia Mold Removal Guide
To use ammonia for mold removal, start by mixing an equal solution of water and ammonia. Apply the solution to the affected area and let it sit for at least 10 minutes.
Scrub the surface with a brush to remove the mold. Finally, rinse the area with clean water and dry thoroughly.
Preparing the Area
Before applying ammonia, remove any items from the area and cover any delicate surfaces that might be damaged.
Ensure all materials and tools you need are at hand. Remember to put on your PPE.
Ideal Conditions for Ammonia Application
The best conditions for using ammonia are in a well-ventilated space with low humidity. Ammonia evaporates quickly, so cooler temperatures can help slow down the evaporation rate and increase contact time with mold.
Applying Ammonia on Various Surfaces
Apply ammonia with a spray bottle for even distribution. For uneven surfaces, a cloth or sponge soaked in the ammonia solution can be used to cover the mold thoroughly.
Exposure Time for Effectiveness
After applying ammonia, it should remain on the surface for at least 10 minutes to kill the mold effectively. However, for more severe infestations, a longer contact time may be necessary.
Cleaning Up After Ammonia Use
Once the mold is removed, clean the area with water to remove any residual ammonia. Dry the area completely to prevent any future mold growth.
Dispose of any cloths or brushes used in the process to avoid spreading mold spores.
Non-Hazardous Alternatives to Ammonia
For those seeking safer alternatives, vinegar or baking soda solutions can be effective against mold.
These substances are less abrasive and toxic compared to ammonia and can be used safely on a variety of surfaces.
FAQs About Ammonia Killing Mold
Can ammonia effectively kill mold?
Yes, ammonia can effectively kill mold on non-porous surfaces when used in a properly diluted solution.
What is the correct ammonia solution to kill mold?
The correct solution is a mixture of equal parts water and ammonia.
Is ammonia suitable for removing mold from porous surfaces?
No, ammonia is ineffective on porous surfaces and is not recommended for mold removal in such cases.
Can ammonia be mixed with bleach to kill mold?
No, ammonia should never be mixed with bleach as it creates toxic fumes that are extremely harmful.
Are there any safety precautions to consider when using ammonia to kill mold?
Yes, always ensure good ventilation when using ammonia, wear protective gear, and never mix it with bleach.
Final Thoughts
Ammonia is effective at killing mold on non-porous surfaces when used in a 50/50 solution with water.
It’s not suitable for porous materials and poses significant health risks, especially if inadvertently combined with bleach, which can create dangerous fumes.
