Does Lysol Disinfectant Spray Kill Mold? The Truth Revealed

Lysol Disinfectant Spray can kill some types of mold on hard, non-porous surfaces, but it’s not a long-term solution for significant mold infestations. While Lysol can disinfect and temporarily eliminate surface mold, it doesn’t address the underlying moisture problems that fuel mold growth, making professional remediation essential for persistent issues.

Lysol and Mold: Understanding the Limitations

Lysol disinfectant spray is primarily designed to kill bacteria and viruses. Its effectiveness against mold hinges on several factors, including the type of mold, the surface it’s growing on, and the thoroughness of the application. Think of it as a temporary surface cleaner, not a mold eradication tool.

Lysol contains ingredients like ethanol and quaternary ammonium compounds, which are known to have antifungal properties. These compounds can disrupt the cell membranes of mold spores, leading to their destruction. However, this effect is usually limited to the surface layer and doesn’t penetrate deeply into porous materials where mold roots can thrive.

Therefore, while Lysol can kill surface mold on hard, non-porous surfaces like tiles, countertops, and sealed wood, it is far less effective on porous materials like drywall, carpets, and upholstery. In these cases, the mold will likely return quickly, even after Lysol application. Addressing the source of the moisture that allows the mold to grow is the most important factor in long-term mold prevention.

When to Use Lysol (and When Not To)

Using Lysol for mold removal can be a short-term solution for small, contained areas on non-porous surfaces. However, for larger infestations, pervasive growth in porous materials, or recurring mold problems, professional remediation is necessary. Remember, using Lysol is primarily a surface treatment, and it does not address the root cause of the mold problem. Attempting to use Lysol to fix a major mold infestation can actually make the problem worse by spreading the spores to new areas.

Here are a few key considerations:

Size of the Infestation: Small spots of mold (less than 10 square feet) on hard, non-porous surfaces might be addressed with Lysol, with proper safety precautions. Larger infestations require professional intervention.
Type of Surface: Lysol is only effective on hard, non-porous surfaces. Porous materials require more specialized cleaning methods and possibly removal.
Underlying Moisture Problem: If you don’t address the source of the moisture, the mold will return, regardless of how much Lysol you use. Fix leaks, improve ventilation, and dehumidify the area.
Health Concerns: Exposure to mold can cause allergic reactions, respiratory problems, and other health issues. Protect yourself with proper safety gear (gloves, mask, eye protection) and consider professional help if you have health concerns or a large mold problem.

Safety Precautions When Using Lysol for Mold

Always prioritize safety when dealing with mold. Even small applications of Lysol can pose risks. Be sure to:

Wear protective gear: Including gloves, a mask rated for mold spores (N95 or higher), and eye protection.
Ventilate the area: Open windows and doors to ensure adequate airflow.
Avoid direct skin contact: Lysol can cause skin irritation.
Follow product instructions carefully: Adhere to the directions on the Lysol label regarding application, contact time, and safety precautions.
Wash hands thoroughly: After handling Lysol and mold, wash your hands with soap and water.

Frequently Asked Questions (FAQs) About Lysol and Mold

Here are some common questions and answers about using Lysol for mold control:

H3: 1. Does Lysol kill black mold?

Lysol can kill surface black mold on hard, non-porous surfaces. However, like other mold types, black mold often grows deeper within materials. Lysol will only address the visible surface mold, and the root of the problem will persist if the moisture source is not addressed and the porous materials are not properly remediated. Black mold can be toxic; therefore, larger infestations should always be handled by professionals.

H3: 2. How long does Lysol need to sit on mold to kill it?

The amount of time Lysol needs to sit on mold depends on the specific product and the manufacturer’s instructions. Typically, the label will specify a contact time of several minutes (usually 5-10 minutes) for disinfection. Allow the Lysol to remain wet on the surface for the recommended duration to maximize its effectiveness.

H3: 3. Can I use Lysol on drywall to kill mold?

No, Lysol is not recommended for drywall. Drywall is a porous material, allowing mold to penetrate deeply. Lysol will only treat the surface, leaving the underlying mold to continue growing. Furthermore, the moisture from the Lysol can exacerbate the problem. Affected drywall typically needs to be removed and replaced, or treated with a specialized antifungal solution designed for porous materials.

H3: 4. Is bleach better than Lysol for killing mold?

Bleach can be effective at killing surface mold, but it’s not always the best option. Like Lysol, bleach is only effective on non-porous surfaces. It can also damage some materials and release harmful fumes. Bleach will not kill mold below the surface. When using bleach, ensure adequate ventilation, wear protective gear, and never mix it with ammonia.

H3: 5. What are the alternatives to Lysol for mold removal?

Alternatives to Lysol for minor mold issues include vinegar, baking soda, and commercial mold-killing products specifically designed for the type of surface you’re cleaning. For larger infestations or porous surfaces, professional mold remediation is the best course of action.

H3: 6. How do I prevent mold from returning after cleaning?

Preventing mold recurrence involves addressing the underlying cause of the moisture. This includes fixing leaks, improving ventilation, reducing humidity with a dehumidifier, and ensuring proper drainage. Regular cleaning and maintenance can also help prevent mold growth.

H3: 7. Can Lysol damage surfaces?

Lysol can damage certain surfaces, especially if used improperly. Always test Lysol on an inconspicuous area before applying it to a larger area. Avoid using Lysol on delicate surfaces like fabrics, painted walls, or finished wood without testing first.

H3: 8. Should I use Lysol to kill mold on wood?

Lysol is generally not recommended for unfinished wood due to its porous nature. However, if the wood is sealed, a light application of Lysol might kill surface mold. Thoroughly dry the wood afterward to prevent further mold growth. Consider using specialized wood cleaners with antifungal properties for better results.

H3: 9. What are the symptoms of mold exposure?

Symptoms of mold exposure can vary depending on the individual and the type of mold. Common symptoms include allergic reactions (sneezing, runny nose, itchy eyes), respiratory problems (coughing, wheezing, shortness of breath), skin irritation, and headaches.

H3: 10. When should I call a professional for mold remediation?

You should call a professional for mold remediation when the infestation is larger than 10 square feet, located in a hidden area (like behind walls or under floors), or if you experience health problems related to mold exposure. Professionals have the expertise, equipment, and safety gear to safely and effectively remove mold.

H3: 11. What is the best way to find the source of mold in my home?

The best way to find the source of mold is to look for areas with moisture problems, such as leaks, condensation, or water damage. Check bathrooms, kitchens, basements, and crawl spaces. You may also need to inspect behind walls or under flooring if you suspect hidden mold. Use a moisture meter to detect dampness.

H3: 12. How does humidity contribute to mold growth?

High humidity levels provide the moisture necessary for mold to thrive. Mold spores are always present in the air, but they need moisture to germinate and grow. Maintaining a relative humidity level below 60% can significantly reduce the risk of mold growth. Using dehumidifiers and ensuring proper ventilation are crucial for controlling humidity.
