The mold is a common problem that not only damages the surfaces of our homes, but can also negatively affect our health. Many chemical products promise to solve the problem, but they are often aggressive and environmentally unfriendly, as well as not a permanent solution.

1. Why to choose a natural anti-mold
Mold can be a persistent and difficult problem to eliminate, but using natural methods offers a number of benefits beyond simple removal. While commercial chemicals are often effective, they contain toxic substances that can pose risks to the environment, human and pet health.
Natural methods, or do-it-yourself mold preventatives, on the other hand, are an environmentally friendly and safe alternative that can address the problem without negative impacts. Here is why to choose natural solutions:
Environmentally friendly: Natural remedies do not release pollutants into the air or surfaces, helping to protect the environment. This choice is especially important at a time when sustainability is critical to the future of our planet.
HEALTH SAFE: Unlike chemical products, natural methods pose no health risks to those living in the home. This makes them ideal for families with young children or pets.
Affordable and accessible: Many of the natural ingredients, such as vinegar, baking soda and lemon, are already present in our kitchens, making these remedies not only effective but also affordable.
Suitable for a variety of surfaces: Natural remedies can be used on a wide range of materials without damaging them, unlike some chemicals that can be too aggressive.
In addition to these benefits, natural remedies also represent a proactive approach to household management. Opting for green solutions means making a responsible choice and contributing to a healthier home environment and a more sustainable future.
2. The most effective natural ingredients to eliminate mold
Here are some natural ingredients you can use to eliminate mold safely and effectively:
- White vinegar: Due to its antifungal properties, vinegar is one of the most widely used remedies against mold. It is especially effective on surfaces such as tile, glass and plastic. Ideal for removing mold from walls vinegar.
Sodium bicarbonate: This ingredient is great for removing mold stains and preventing their reappearance. It also eliminates unpleasant odors.
Hydrogen peroxide (hydrogen peroxide): At a concentration of 3 percent, it is a powerful antifungal that removes mold spores without damaging surfaces.
Tea tree essential oil: This natural oil has antimicrobial properties and is effective for treating areas affected by mold.
Lemon: With its disinfectant power and pleasant scent, lemon is perfect for removing light mold on washable surfaces.
Remember: these natural ingredients are great for eliminating mold on the surface, but if the root cause is moisture trapped in the walls, it is essential to intervene with a long-term remediation system. A dehumidifying and breathable plaster, such as Afontermo, prevents the return of mold and provides lasting protection.

4. Tips for preventing the formation of mold
Eliminating mold is essential, but preventing its formation is even more important for maintaining a healthy and safe home environment in the long term. Mold thrives in damp, poorly ventilated rooms, but with a few habits and practical steps, you can prevent its occurrence. Here are the best tips for preventing it:
Ventilate rooms regularly:
Stagnant air promotes moisture buildup. Open windows at least 10 to 15 minutes a day, especially after steam-producing activities such as cooking or showering. In winter months, choose the warmest times of day to avoid heat loss.Keep humidity levels under control:
The ideal humidity level for a home is around 40-60%. Use a dehumidifier in the most humid rooms, such as bathrooms, kitchens or basements. You can also place moisture-absorbing salts in critical spots to counteract condensation.Repair any seepage and leaks:
Water seepage from roofs, walls or pipes is a major cause of persistent dampness. Check the condition of walls, ceilings, and plumbing systems regularly for leaks or damage. Taking prompt action can prevent more serious problems.Use breathable materials:
During renovation or maintenance work, choose breathable paints and plasters. These materials allow walls to “breathe,” reducing moisture buildup and preventing mold growth.Avoid accumulation of furniture against cold walls:
Leaving a space of at least 5-10 cm between furniture and outside or cold walls promotes air circulation, preventing condensation and mold from forming behind cabinets and bookcases.Check heating and ventilation systems:
Even heat distribution within rooms helps prevent temperature differences that cause condensation. If you have a controlled mechanical ventilation (MCV) system, make sure it is in perfect working order.
Ventilating, dehumidifying, and protecting surfaces are key actions to slow mold growth, but when the problem is related to persistent dampness in walls, a structural solution is needed.
