Efficiently Removing Early Onset Mildew Using Microfiber Cloths and Chlorine Dioxide Solution made with Envirotab

Early onset mildew growth on walls and other surfaces is a common household problem that needs immediate attention. If left unaddressed, mildew can spread rapidly, causing damage to the affected areas and potentially posing health risks. Fortunately, there are effective methods to combat this issue using microfiber cloths and a chlorine dioxide solution made with Envirotab. This article outlines the steps involved in safely and efficiently removing early onset mildew.


  1. Understanding the Problem: Mildew, a type of fungus, thrives in damp and poorly ventilated areas. It often appears as dark spots or patches on walls, ceilings, or other surfaces, accompanied by a musty odor. Early intervention is crucial to preventing further damage and health hazards.

  4. Chlorine dioxide solution made with Envirotab: Envirotab is eco-friendly, chlorine dioxide-generating cleaning solution tablet that effectively eliminates odors, bacteria, mold, and mildew.
  5. Personal protective equipment (PPE): Wear gloves, safety goggles, and a mask to protect yourself from mold spores and chemicals.

  7. Removing Mildew with Microfiber Cloths: Begin by gently wiping the affected areas with a dry microfiber cloth. This step helps remove loose mildew spores and prevents the spread of mold during the cleaning process. Dispose of the cloth properly after use.
  8. Preparing the Chlorine Dioxide Solution: Ensure that you wear appropriate PPE during this stage. In a container of 32 fluid ounces of clean water - a pail, PET Trigger or Pump-up Sprayer, add (1) 4g Envirotab Tablet, apply the trigger or cover and allow to dissolve for 1-2 minutes.
  9. Applying the Chlorine Dioxide Solution: Spray the solution on the affected area: walls, trim, doors, windowsills, etc. Allow to set for 2-3 minutes and wipe with a microfiber cloth. Some paints. especially flat and eggshell latex paints may not come completely clean, but rest assured that the treated mildew will not regrow. If you are applying this to carpets, fabrics, upholstery, clothing or other soft surfaces, please test the material against the solution before treatment to ensure its colorfastness.

What You Can Do to Keep Mustiness, Mildew and Mold from Invading your Home

A home humidity gauge will help ensure a mildew-free environment

Mildew, a common problem in many households, is a type of fungus that thrives in warm, damp, and poorly ventilated areas. It can be found on various surfaces, such as walls, ceilings, fabrics, and even food. Mildew forms when microscopic spores land on moist surfaces and start to grow and spread. The presence of mildew not only causes an unpleasant musty odor but can also lead to health issues like allergies, respiratory problems, and skin irritation.


To prevent mildew from forming and ensure it does not return, there are several proactive steps you can take. First and foremost, it is crucial to reduce moisture and increase ventilation in your living environment. Proper ventilation can be achieved by opening windows, using exhaust fans, or investing in a dehumidifier. Additionally, regular cleaning and maintenance are key to controlling mildew growth. Pay attention to areas prone to moisture, such as bathrooms, kitchens, and basements, as they can be breeding grounds for mildew. Use a mildew remover or a mixture of bleach and water to clean affected surfaces thoroughly.


Another strategy to inhibit mildew growth is to control the humidity levels in your home. Keep the humidity below 50% by using air conditioners or dehumidifiers, especially during humid seasons. Additionally, fixing any water leaks promptly, whether it's from pipes or a roof, is essential as it prevents moisture buildup and the development of mildew.


Properly drying and airing out fabrics, such as clothes and towels, is also crucial in preventing mildew. Avoid leaving wet or damp fabrics sitting for an extended period. If possible, hang them outside in the sunlight, which not only helps to dry them but also kills the mildew spores.


Mildew is a persistent fungus that thrives in moist environments. To prevent its formation and avoid its return, it is essential to maintain proper ventilation, control humidity levels, and promptly address any water leaks. Regular cleaning, especially in moisture-prone areas, along with proper drying and airing out of fabrics, will help keep mildew at bay. By taking these preventative measures, you can create a healthier and mold-free living environment for you and your family. And when you need to remove it, use Envirotab!
