Before You Buy Mold Remover 

Though mold-removing products are tried-and-true methods for getting rid of spores and mildew, many of them have chemicals that some users may not desire. Particularly, products with heavy-duty bleach can leave harsh aerosols behind that can potentially harm the lungs and sinuses. Some other chemicals that are included in mold removers can cause harm to users if breathed in, swallowed, or exposed to the eyes.

One way to ensure these chemically enhanced products are not needed is to frequently clean areas that are exposed to moisture since this is where mold and mildew love to grow.

How We Chose the Best Mold Removers 

We researched the most sought-after mold and mildew removers in their respective categories and discovered that the best options are often determined by what kind of mold they treat, cleaning time, ease of application, compatibility with multiple surfaces, and other special features included by select brands.

While searching for the best mold killers, the ones that are capable of treating mold spores and mildew, have spray applications, and clean surfaces instantly were the most popular among users. To ensure our list provided versatile options, we chose mold removers that work on wood, composites, vinyl, metal, fabrics, plastic, stucco, wicker, concrete, stone, brick, and asphalt.

Even though many are considered to be mold and mildew removers, some are also meant for use on viruses, bacteria, algae, dirt, moss, and grime. Select options require dilution before use or do not come with spray bottles, and many options have built-in spray nozzles or can be connected to garden hoses for easy application.

Our Top Picks

Below is a list of some of the best mold removers that you can employ in or on your home to kill fungus and get back to a happier, healthier home.

However, none of these mold killers will work for long if you don’t address the problem that brought on the mold. Even if the affected material is removed, mold can grow back in as little as 2 days if the moisture source is still present.

Or, DIY Your Own Mold Remover

Making a homemade version is thrifty, (can be) natural, and low waste. Not to mention, it’s very Bob Vila! This section covers how to make comparable mold-removal products at home with household materials.

One way to kill mold and mildew is by pouring a bottle of 3 percent hydrogen peroxide into a household spray bottle, spraying the desired surface, leaving it on for 10 minutes, then scrubbing vigorously until the stains fade. Hydrogen peroxide is antifungal, antiviral, and antibacterial, making it effective for allergenic mold removal on appliances, bathroom fixtures, some flooring types, and even wall surfaces.

Another tried-and-true method is to use white vinegar. This substance is effective at deodorizing, cleaning, and disinfecting while killing 82 percent of mold varieties. Simply pour undiluted white vinegar into a household spray bottle, spray on the desired surface, and leave for 1 hour. Then, rinse with water. Though this solution is effective, it may leave a slight vinegar smell behind after cleaning.

What to Consider When Choosing a Mold Remover

Before donning rubber gloves and spraying down a gross, moldy surface, keep in mind that the best mold remover and the best technique depends on the type of material that’s being treated for mold growth.

Location of Mold

Some molds are easier to tackle than others. If mold growth ends up on fabrics like curtains, for example, users can usually throw them in a washing machine with the proper mold remover. But, if the mold is under a kitchen cabinet, the job can be more difficult to remedy.

Mold grows on and eats away at organic surfaces. If it has access to drywall, like behind a sink cabinet, it can feed on the paper face and do a lot of damage. It could even require more time or labor such as removing the cabinets, drywall, and insulation and treating the mold in the cavity behind it.

In other cases, like on a home’s siding, some old-fashioned elbow grease might be all that is needed. Users can simply spray the siding with a mold remover and brush it clean.

Mold Type

It doesn’t always matter what kind of mold users have in their home. Most mold removers are effective at removing any of the common types. But, some molds are more dangerous than others and could require professional intervention.

Black mold removal in particular can be a serious problem. Stachybotrys, its official name, is a toxic mold that is especially harmful to the respiratory system. It typically requires a consistent moisture source to grow. From there, it can spread quickly. Users may recognize it by its mildewlike odor or its slimy texture. If users are dealing with black mold, it might be a good idea to call in the pros.

Cleaning Time

The amount of time it takes the best mold and mildew removers to do their job can vary from one product to the next. With some, users apply the treatment once and leave it. Others require reapplication after 15 minutes. Either way, once applied, the mold killer goes to work killing the fungus before scrubbing it or wiping it away.

In the case of a soapy detergent, users might not let the solution sit at all before getting down to business. These detergents require brushing to loosen the mold and allow the mold killer to soak into the surface.

Application

There are a few ways to apply a mold killer. Choosing the right method for a particular mold problem can make all the difference. Some products come in spray bottles. They’re great for smaller mold invasions that don’t require multiple applications or treatments.

Other mold killers come in concentrates that are mixed in a separate container. This allows you to adjust the strength between applications. You can apply these with a brush, a sponge, or a mop. Or, pour the solution into a spray bottle.

Other products, meant for outdoor use, attach to the end of a garden hose. These mold killers mix with the water stream to produce a high-volume spray to hit surfaces such as driveways, decks, or siding.

Ease of Use

Mold’s a nasty substance, and remediation can be challenging. But, you can at least choose a product that’s easy to use. Typically, the easiest-to-use products are spray solutions. Simply point the bottle at the problem and shoot.

If you’re treating the exterior of a house, it’s a lot easier to use a hose attachment that pumps the solution through a hose’s stream. You can cover a larger area in less time than you would with a spray bottle.

A particular mold problem might be best suited to the products that you can spray and walk away from. This can be a huge advantage in tight areas like sink cabinets or behind toilets.

FAQs 

If you still have questions about the best mold removers, that’s OK. There’s a lot to know. The following are answers to some of the most frequently asked questions. If you don’t find your answer here, contact the manufacturer.

Q. What does mold smell like?

Many molds are odorless. Black mold, on the other hand, has a damp, earthy, mildewlike smell, similar to soil.

Q. What does black mold look like?

Black mold has a spotty appearance and is usually greenish-black in color, though it can often look brown or gray.

Q. Does mold come back after cleaning?

If you don’t stop the source of the moisture, mold will most definitely return. Also, if you simply bleach the surface of a material like drywall, you won’t remove the roots of the mold that are deep inside. The mold may rebloom within a day or two.

Q. What are the effects of mold?

Mold has a variety of effects on your home and your health. It can turn surfaces like wood and drywall into dust. It can also cause respiratory problems, coldlike symptoms, eye irritation, and skin irritation.
