Oct 17, 2024 | Mold Advice & Tips | 0 comments

San Diego County’s coastal areas are known for their beautiful beaches and pleasant climate. However, these same factors that make the region so appealing also create ideal conditions for mold growth, particularly in showers.

Understanding why mold thrives in these coastal environments and how to combat it is crucial for maintaining a healthy home.

We get calls about this problem almost every day from homeowners in the beautiful beach towns of Carlsbad, Encinitas, La Jolla, Oceanside and the city of San Diego so we created this quick guide to help.

High Humidity Levels

The coastal areas of San Diego County experience higher humidity levels due to their proximity to the Pacific Ocean. This increased moisture in the air creates a perfect environment for mold to flourish, especially in enclosed spaces like bathrooms.

Warm Temperatures

San Diego’s mild climate, with temperatures often ranging between 60-80°F year-round, provides an ideal temperature range for mold growth. Combine this with the humidity, and you have a recipe for persistent mold issues.

Poor Ventilation

Many older homes in coastal San Diego may lack adequate ventilation systems, trapping moisture in bathrooms and creating a breeding ground for mold.

Salt in the Air

The salt content in the coastal air can accelerate corrosion and breakdown of surfaces, creating small cracks and crevices where mold can take hold.

Weekly Cleaning

Perform a more thorough cleaning once a week:

  • Scrub the shower floor, shelves, and glass doors
  • Clean the walls and fixtures
  • Pay special attention to corners and grout lines where grime accumulates
  • Use a mild cleaner suitable for your shower surfaces

Monthly Deep Cleaning

Once a month, conduct a more intensive cleaning:

  • Clean the shower walls, shower liner, and showerhead thoroughly
  • Scrub grout lines with a specialized cleaner
  • Check and clean the drain
  • Wash fabric shower curtains (if applicable)

How to Clean Mold in Showers

1. Vinegar Solution

Mix equal parts white vinegar and water in a spray bottle. Apply to moldy areas, let sit for an hour, then scrub with a brush and rinse thoroughly.

2. Baking Soda Paste

Create a paste using baking soda and water. Apply to affected areas, scrub gently, and rinse. This method is particularly effective for grout lines.

3. Hydrogen Peroxide

Use a 3% hydrogen peroxide solution in a spray bottle. Apply to moldy areas, let sit for 10 minutes, then scrub and rinse.

4. Commercial Mold Cleaners

For stubborn mold, use a commercial mold cleaner following the manufacturer’s instructions. Ensure proper ventilation when using these products.

Yearly Maintenance

Annually, perform these tasks:

  • Deep clean all surfaces
  • Reseal grout lines
  • Replace shower curtains and bath mats
  • Inspect for any damage or areas prone to mold growth

Preventing Mold Growth in Coastal San Diego Showers

Improve Ventilation: Install a high-quality exhaust fan in your bathroom and run it during and for at least 30 minutes after showers.

Use a Squeegee: After each shower, use a squeegee to remove excess water from walls, doors, and floors.

Keep Surfaces Dry: Hang towels and bathmats to dry completely between uses. Consider using a dehumidifier in your bathroom.

Regular Cleaning: Clean your shower weekly with mold-inhibiting products to prevent spore growth.

Fix Leaks Promptly: Address any plumbing leaks immediately to prevent excess moisture buildup.

Use Mold-Resistant Products: When renovating, choose mold-resistant shower curtains, grout, and paint.

Control Indoor Humidity: Use air conditioning or dehumidifiers to keep indoor humidity levels below 60%.

By understanding the unique challenges of coastal living in San Diego County and implementing these cleaning and prevention strategies, homeowners can effectively combat mold growth in their showers.
