How to Treat Mold Growing on Your Walls

Clean Mold Stains Effectively, Then Combat Their Return with Puraclenz

Discovering mold ¹ on your walls can be alarming. Whether on drywall, tile, or painted surfaces, mold growth signals excess moisture and poor air quality. Fortunately, with the right approach, you can remove mold stains and fight the conditions that allow it to come back. This guide walks you through proper cleaning methods and how installing a Puraclenz air purifier for mold helps you maintain cleaner air and surfaces long term.

Step 1: Address the Source of Moisture

Before tackling any visible mold, identify what's causing it to grow. Common sources include:

• Roof or plumbing leaks
• Poor ventilation in bathrooms or laundry rooms
• Indoor humidity above 60%

Fixing these moisture problems is critical before cleaning, or mold can return.

Step 2: Remove the Mold Stains

Once the area is dry and the moisture issue is resolved, it’s time to clean the mold stains from your walls.

You’ll need:

• Gloves and mask
• White vinegar, hydrogen peroxide, or an EPA-registered mold cleaner
• Spray bottle
• Scrub brush or sponge
• Clean towels

Cleaning steps:

1. Apply the cleaner generously to the stained area.
2. Let it sit for 10–15 minutes to break down the mold.
3. Scrub until the stains are removed.
4. Wipe clean with a towel and allow the surface to dry completely.

Avoid using bleach alone—it may fade the stain but won’t deactivate deeper mold colonies.

Step 3: Use Puraclenz to Fight Mold Spores in the Air and on Surfaces

After cleaning, Puraclenz helps combat airborne mold spores that can settle and grow again. Puraclenz purifiers use advanced PCO purification technology to continuously deactivate pollutants, including mold spores, in the air and on exposed surfaces.

Unlike a traditional air filter for mold that only captures spores, Puraclenz proactively neutralizes them before they can spread. This makes it an ideal air purifier for mold and a powerful addition to your mold treatment strategy.

Why Puraclenz Works:

• Reduces airborne mold spores that contribute to surface regrowth
• Deactivates mold on walls and hard-to-reach areas without using ozone
• Designed for continuous use as an air purifier for home environments
• Requires no filters to trap mold; it treats the air and surfaces directly

In independent lab tests, Puraclenz showed a 95.1% reduction of airborne Aspergillus brasiliensis, a black mold surrogate, and 99.75% reduction of Candida albicans spores on surfaces—even when over 8 feet away from the purifier.

Long-Term Mold Management Tips

• Maintain humidity between 30–50% with a dehumidifier
• Use exhaust fans during and after showers
• Repair water damage promptly
• Clean mold-prone surfaces regularly
• Keep your mold purifier running continuously in high-risk areas

Conclusion

To combat mold ¹ effectively, start by removing visible mold stains, then improve your indoor environment with technology that deactivates mold spores. A Puraclenz air purifier for home use can serve as a proactive defense against airborne and surface pollutants, helping you maintain cleaner walls, cleaner air, and peace of mind.
