How to Prevent Mold and Mildew From Coming Back

How to Prevent Mold and Mildew From Coming Back

If mold and mildew keep returning after cleaning, excess moisture is usually the underlying problem. Cleaning removes the existing staining, but controlling humidity, improving ventilation and keeping surfaces dry can help prevent mold and mildew from quickly returning.

The most effective approach combines regular cleaning with moisture control.

Keep Surfaces Dry

Mold and mildew thrive in damp environments, so one of the simplest preventive measures is helping wet surfaces dry more quickly.

Pay particular attention to:

• Showers and bathtubs

• Tile and grout

• Bathroom floors

• Sink areas

• Basements

• Concrete

• Other moisture-prone surfaces

After showers or baths, remove excess water from walls, glass and other surfaces when practical.

Improve Bathroom Ventilation

Bathrooms are especially susceptible to recurring mold and mildew because showers create significant humidity.

To improve ventilation:

• Run the bathroom exhaust fan during showers

• Continue running the fan afterward

• Open the bathroom door when appropriate

• Open a window when weather permits

• Allow shower doors or curtains to remain open so surfaces can dry

Better airflow helps moisture leave the room instead of remaining on surfaces.

Repair Water Leaks

Even a small plumbing leak can create a consistently damp environment.

Check for leaks around:

• Sinks

• Toilets

• Bathtubs

• Showers

• Faucets

• Pipes

• Basement plumbing

Repair leaks promptly rather than repeatedly cleaning the mold or mildew that develops around them.

Control Indoor Humidity

High indoor humidity can contribute to mold and mildew even when there isn't an obvious water leak.

Basements and bathrooms can be particularly susceptible.

Improving ventilation, using air conditioning or using a dehumidifier when appropriate can help reduce excessive indoor moisture.

Keep Showers, Tile and Grout Clean

Soap residue, body oils and other buildup can accumulate on shower surfaces.

Regularly clean:

• Shower walls

• Tile

• Grout

• Bathtubs

• Glass shower doors

• Corners and seams

Routine cleaning helps prevent heavy staining and buildup from developing.

Use a Squeegee After Showering

A simple shower squeegee can remove a significant amount of water from tile and glass.

Removing this water helps surfaces dry faster and reduces the amount of time they remain damp after each shower.

Address Basement Moisture

If mold or mildew repeatedly appears in a basement, look beyond surface cleaning.

Possible causes include:

• High humidity

• Foundation leaks

• Groundwater intrusion

• Condensation

• Plumbing leaks

• Poor ventilation

Correcting the source of basement moisture is important for preventing recurring problems.

Improve Outdoor Drainage

Outdoor mold and mildew staining can develop on concrete, stone and other surfaces that remain damp.

Help reduce moisture by:

• Improving drainage

• Preventing standing water

• Keeping gutters and downspouts functioning properly

• Increasing airflow where practical

• Correcting sources of repeated water exposure

Shaded areas may naturally take longer to dry and may require more frequent cleaning.

Clean Mold and Mildew When You First Notice It

Don't wait for a small stained area to become a larger cleaning job.

Natural Armor All-Natural Mold & Mildew Cleaner is a ready-to-use, bleach-free formula designed to help remove mold and mildew stains from compatible surfaces.

Regular attention to moisture-prone areas can make mold and mildew staining easier to manage.

What If Mold Keeps Returning?

If mold or mildew repeatedly returns despite cleaning and moisture control, there may be a hidden source of moisture.

Possible problems include:

• Water leaking behind walls

• Roof leaks

• Hidden plumbing leaks

• Persistent water intrusion

• Wet building materials

Extensive or hidden mold growth may require professional assessment rather than repeated surface cleaning.

Clean the Surface — Then Control the Moisture

The key to preventing recurring mold and mildew is understanding that cleaning and prevention are two different steps.

First, clean the existing mold and mildew staining.

Then address the moisture, humidity or ventilation problem that allowed it to develop.

That combination provides a much better long-term approach than simply cleaning the same area repeatedly.
