The Best Methods for Getting Rid of Mold (Safely and Effectively)
Mold is a common household problem. However, it can quickly become serious if left untreated. Not only does it look and smell unpleasant, but it can also impact your health, especially if you have allergies or respiratory issues.
The good news? Most small mold problems can be handled at home if you act quickly and use the right methods. The key is not just removing the mold, but fixing the moisture problem that caused it in the first place.
What Causes Mold in Your Home?
Mold thrives anywhere there’s moisture, warmth, and poor airflow. Common problem areas include:
- Bathrooms and kitchens
- Basements and crawl spaces
- Around leaks (roofs, pipes, windows)
- Damp carpets or upholstery
Mold can start growing within 24–48 hours after water exposure, which is why quick action is so important.
The first step in getting rid of mold is identifying where the mold is growing. Mold can grow anywhere there is moisture, so it’s important to check all areas of your home for mold growth. Some common places to find mold are in basements, attics, and bathrooms. Once you’ve identified where the mold is growing, you can begin the process of removing it.
Step 1: Protect Yourself First
Before you start cleaning, safety matters. Wear protective gear. This is especially important if you’re dealing with larger areas of mold.
Experts recommend wearing:
- Gloves
- Goggles
- A mask (like an N95)
This helps prevent breathing in mold spores or getting them on your skin.
Skip DIY cleanup if:
- You have asthma or respiratory issues
- The mold covers a large area (generally more than ~10 sq. ft.)
- It’s inside the walls or HVAC systems
Step 2: Fix the Moisture Problem
This is the step most people skip, and it’s why mold keeps coming back.
Mold will return unless you:
- Repair leaks
- Improve ventilation
- Lower indoor humidity
- Use fans or dehumidifiers
Simply cleaning mold without fixing the cause is only a temporary solution.
Step 3: Use the Right Cleaning Method
For small areas of mold, you don’t need anything fancy. You can use soap and water for small spots.
Best cleaning options:
Bleach
Bleach is one of the most common and effective ways to remove mold. To use bleach, mix one cup of bleach with one gallon of water. Once the mixture is mixed, apply it to an area with mold growth. This mixture will kill the mold and help to remove it from the surface. The Clorox company recommends wearing gloves and goggles when using this mixture, as it can be harmful to the skin and eyes.

Pour white vinegar onto a cloth and wipe an area with mold development to use it as a disinfectant. This should be done in a well-ventilated area, as the vinegar smell can be strong.

Ammonia is a chemical that can be used to remove mold. To use ammonia, mix one cup of ammonia with one gallon of water. Once the mixture is mixed, apply it to an area with mold growth. This mixture will kill the mold and help to remove it from the surface. Be sure to wear gloves, goggles, and a mask when using this mixture, as it can be harmful to the skin, eyes, and lungs.

Each of these substances will kill mold and help to prevent it from coming back. Just be sure that you’re using them safely and following the instructions on the label. Scrub the surface thoroughly and dry it immediately afterward.
⚠️ Important:
- Never mix bleach with ammonia or other cleaners
- Always ventilate the area
Step 4: Remove Porous Materials
Some items can’t be fully cleaned once mold gets inside them.
You may need to throw out:
- Carpet
- Drywall
- Ceiling tiles
- Insulation
If it can’t be completely dried within 24–48 hours, it should be removed.
Step 5: Dry Everything Completely
Drying is just as important as cleaning.
- Open windows and doors
- Use fans and dehumidifiers
- Wipe down surfaces thoroughly
Mold thrives in damp environments, so drying fast is key to stopping regrowth.
Step 6: Don’t Just Cover Mold
Painting or caulking over mold doesn’t solve the problem.
It may look better temporarily, but the mold will continue growing underneath and eventually come back.
Always remove mold completely before repainting or sealing surfaces.
When to Call a Professional

Consider calling a pro if:
- Mold is widespread
- It’s caused by flooding
- It’s inside the walls or ductwork
- You keep seeing it come back
