How to Remove Mold From Every Corner of Your Home

Mold spores are everywhere, and they only need moisture and warmth to activate and start growing into a mold colony. This can occur on various surfaces, including wood, tile, and sheetrock walls.

Mold can appear in different colors, such as black, green, brown, or white. When dealing with a large mold colony, it’s crucial to identify the type of mold before attempting to clean it, considering potential health effects on you and your family.


Understanding Mold and Mildew in Your Home

Mold can grow in your home when there’s excess moisture, especially if it persists over time. It typically shows up on walls, ceilings, and floors, particularly in areas with poor moisture control like basements, shower walls, and windowsills.

Mold and mildew are essentially the same thing, with “mildew” commonly used to describe minor mold issues, like on shower tile grout.

While some molds can become toxic if left untreated, they usually cause allergic reactions, asthma, and respiratory problems, posing a greater risk to children, the elderly, and those with respiratory issues or weakened immune systems.

Mold can take various shapes and colors, but it often appears in shades of black, white, green, or blue. However, these colors don’t accurately determine the mold species.

Understanding Different Types of Mold

  1. Black Mold: Found in houses with severe moisture damage, black mold isn’t harmful itself, but it can produce mycotoxins that may harm people and pets. Exercise caution when removing any mold, especially if it’s widespread.
  2. White Mold: Common in cool, damp environments like basements, white mold is sometimes mistaken for efflorescence, a mineral deposit on surfaces due to water seepage. You can differentiate them by spraying with water—mineral deposits dissolve, while white mold does not.
  3. Blue Mold: Appears in damp areas, especially on bathroom walls and ceilings, due to moisture from steamy showers. The conditions after such showers provide an ideal environment for the formation and growth of blue mold.
  4. Green Mold: Like blue mold, green mold is prevalent in damp areas, such as shower walls and corners. It can be removed by scrubbing with a bleach solution, similar to most molds.

It’s important to clean mold off walls promptly once discovered. Even if you can’t see mold growth, there are signs of potential problems that require attention:

  1. Musty Smell:
    • Detecting an unpleasant odor indicates a mold problem that needs addressing.
  2. Neglected Leaks:
    • Overlooking leaks from faucets or roofs can contribute to mold growth.
  3. Soft or Damp Walls:
    • Walls that feel soft or damp may indicate interior mold growth that will soon become visible.
  4. Moisture Accumulation:
    • Prolonged moisture on walls due to poor ventilation signals a potential mold issue.

Removing Mold from Shower Tile and Grout

Dealing with mold on shower tile and grout can be tackled effectively with the right approach. Follow these steps to get rid of mold:

  1. Apply Cleaner:
  2. Wait Before Scrubbing:
  3. Rinse with Hot Water:
    • Rinse the area with hot water, and either wipe it dry or let it air dry with the shower curtain or door open to allow steam and moisture to escape.

Removing Mold from Walls and Ceilings

If you notice mold on walls or ceilings made of sheetrock or plaster, you can eliminate it without replacing any materials. However, if the mold is on a highly porous surface like ceiling tiles, it’s advisable to replace them promptly.

Expert Tip: Wear eye protection to prevent cleaners from splashing into your eyes when removing mold from ceilings or overhead areas.

  1. Clean the Surface:
    • Put on your protective gear and ensure good ventilation. Mix a small amount of dish detergent, like Dawn Ultra Dishwashing Liquid, with water. Use a sponge apply in small circular motions.
  2. Rinse and Let Dry:
    • Clean the sponge thoroughly, dip it in clean water, and wring it out before wiping the surface clean. Allow it to air dry completely.
  3. Apply Water and Bleach Solution:
    • Mix ¾ cup of chlorine bleach with a gallon of warm water (or 3 tablespoons of bleach in 1 quart of water for smaller spots). Apply the mixture to the stains with a brush or sponge.
  4. Let Sit and Scrub:
    • Allow the water-bleach solution to sit for five minutes, then gently scrub the moldy spots using small circular motions with the sponge or brush.
  5. Rinse and Air Dry:
    • Use warm water to wash the area clean, blot dry with a clean cloth, and let it air dry.

Removing Mold from Fabric

When mold appears on machine-washable fabric items like clothing or towels due to prolonged exposure to humidity, follow these steps:

Expert Tip: For non-machine washable fabric, seek help from your dry cleaner to remove stubborn mold spots.

  1. Brush Off Excess Mold:
    • Take the item outside to prevent mold spores from entering your home. Wear protective gear, then gently use a dry cloth, brush, or paper towel to loosen and remove excess mold.
  2. Treat Spots with Liquid Laundry Detergent:
    • Rub a drop or two of liquid laundry detergent with your gloved fingers. Wash the item in the washing machine on the hottest setting safe for the fabric, adding chlorine or non-chlorine bleach as per the care instructions.
  3. Air Dry:
    • Avoid tumble drying until you are certain that the mold spots are completely removed.

Removing Mold from Basement/Concrete Walls

Step 1: Prepare the Area

Identify mold by its appearance on basement walls, usually as black, white, or bluish patches. Remove items near the affected areas, such as carpeting or cardboard boxes. Dispose of affected items, and consider cleaning salvageable furniture. Clearing the space allows for effective mold removal.

Step 2: Start Scrubbing

Use bleach, mixed with three parts water, to create a solution for scrubbing. Wear rubber gloves, safety goggles, and a respirator or dust mask for protection. Scrub the mold-affected wall vigorously with the bleach solution until the mold disappears. Let the solution sit for a few minutes on tough areas. For stubborn mold, combine a formulated mold remover with the bleach solution.

Safety Alert! Ventilate the basement, wear old clothes, and take precautions to avoid contact with bleach.

After scrubbing, dry the walls with a towel and inspect for any remaining mold. Return moved items to the basement, ensuring nothing with mold is reintroduced. Following these steps diligently helps prevent a recurrence of mold issues.

How to Prevent Mold Growth and Natural Remedies for Removal

Preventing Mold Growth

The Environmental Protection Agency (EPA) highlights that controlling moisture is key to managing indoor mold growth. Follow these steps for effective prevention:

  1. Use Dehumidifiers:
    • Maintain humidity levels below 50% by employing dehumidifiers. Choose the right capacity, such as a 10-pint removal capacity for a 500-square-foot room, with an additional 4 pints for every extra 500 square feet.
  2. Ventilation is Crucial:
    • Ensure moisture-generating sources like bathroom fans and clothes dryers have vents leading outside.
  3. Enhance Bathroom Ventilation:
    • Open doors and windows during showers to assist bathroom exhaust fans in moisture removal. Dry or squeegee the shower after use and leave it open to expedite drying.
  4. Shower Curtain Care:
    • Stretch out the shower curtain after use and regularly reseal bathroom tile grout lines for waterproofing.
  5. Avoid Damp Storage:
    • Refrain from storing items in damp places, especially in basements or attics. If airtight storage isn’t possible, consider alternative storage options.

Natural Remedies for Mold Removal

If you prefer natural solutions, hydrogen peroxide and vinegar can be effective, though they may take longer than bleach and may not work on all types of mold or surfaces:

  1. Hydrogen Peroxide:
    • Pour a 3% solution of peroxide into a spray bottle and apply to the affected area. Let it sit for 10 minutes, then scrub the mold away.
  2. Vinegar:
    • Pour undiluted white vinegar into a spray bottle, apply to the moldy area, and let it sit for an hour. Wipe the area clean with water and allow it to dry.

When to Seek Professional Help

Call a mold removal professional under the following circumstances:

  1. Widespread Mold:
    • If the mold covers an area larger than approximately 2 feet by 2 feet.
  2. Persistent Mold Spots:
    • If dealing with numerous mold spots, as it may indicate a larger moisture issue.
  3. Moisture Problem:
    • When facing persistent mold issues, consult a contractor specializing in water damage restoration or waterproofing to assess and address the underlying moisture problem.
