Kill Mold With Vinegar

white vinegar with cleaning tools

Got mold? Kill mold with vinegar. We are always on the hunt for natural, effective solutions for cleaning mold. Our favorite the household staple: Vinegar. Vinegar is a powerful mold killer. According to ServiceMaster Restoration and Cleaning, the mild acid in vinegar kills about 82% of known molds and can help prevent future outbreaks. Common places you can find mold in your home are on drywall, the foundation, the gutters, HVAC systems, and the roof.

While you can remove small amounts of mold using vinegar, it is best to hire professionals when necessary or when dealing with toxic black mold known as cladosporium. Besides a crisis, such as a flooded home, the Environmental Protection Agency (EPA) advises hiring professionals when the area mold covers is about 10 square feet or more.

Vinegar possesses natural antifungal and antibacterial properties. The acetic acid that is present in vinegar has a decently strong pH of 2.5 enabling it to disrupt and stop the growth of mold, fungi, and other organisms. This artificial chemical free cleaning alternative means that during this process, no chemical resistant microbes are created which is often the case when using bleach.


Vinegar is a better choice than bleach for killing mold, for a variety of reasons. The most important reason is that the application of bleach will most likely leave behind spores that have grown to a high level, allowing them to multiply without competition. The EPA doesn’t recommend bleaching mold to kill or remove it. The application of bleach will most likely leave behind spores that have grown to a high level.

ServiceMaster states:

“..bleach only kills the surface mold and not the membrane beneath. This means that the mold will come back. The mold membranes will actually grow deeper into porous surfaces such as wood or drywall if bleach is applied to them.”

First, keep the apple cider vinegar aside for salad dressing. Regular white distilled vinegar is usually sold at five percent acidity to clean mold. You can also use “cleaning vinegar”, which typically has six percent acidity. Both can effectively kill mold and are regularly sold at a variety of grocery and big box stores. Additionally, generic or store brands can be as effective as the commonly reached for name brand vinegars


For maximum effectiveness, you can leave the vinegar on the mold for 60 minutes. This allows ample time for the vinegar to saturate any present mold. Then, wipe or scrub the mold with paper towel or a disposable sponge, specially designed to trap microbes. Using a regular rag or sponge risks the spread of mold spores throughout your home.

For follow-up treatments where mold is present use the same technique once a week. For preventative methods you can do a vinegar treatment on mold prone areas once every 2-4 weeks.

Like with any cleaning product, we recommend that you wear gloves as the acidity of vinegar can cause skin irritation. When cleaning up any mold you must use goggles, and a mask to protect your skin and airways from mold. Vinegar’s acidity can cause damage to some surfaces. We do not recommend vinegar being used on natural stone, waxed timber, cast iron, or aluminum.

This is where Homebiotic Probiotic Spray comes in! It is the perfect end to your natural cleaning routine, replenishing the population of beneficial microbes keeping your home cleaner, longer. Keeping a healthy balance of microbes in your home ensures your home microbiome stays healthy and keeps all microbe populations in check.

Do Not Clean Mold With Bleach: Here’s Why

Do Not Clean With Bleach: Here's Why | Blog

A fairly common experience for homeowners is to find a small patch of mold and immediately reach for some sort of antibacterial cleaner, namely bleach, to deal with the issue. But did you know, you shouldn’t clean mold with bleach? We know, this raises a whole host of questions about modern cleaning practices:

  • But what if you’re cleaning your house all wrong?
  • What if you’re making it easier for the spots of mold to take over?
  • What if there is such a thing as too clean or too sterile?

Sadly, mold removal is never as simple as it looks on TV. But the good news is that it’s straightforward and safe to tackle small outbreaks of the mold without having to call in a professional – and without dealing with bleach fumes.

We’ve all done it. Noticed a spot of mold in the shower, sprayed bleach then scrubbed away the discolored patch on the wall or grouting. That’s that.

Bleach works fantastically on tiling, and other hard surfaces, where moisture and humidity provide a friendly environment for mold. But bleach-based cleaners are not suitable for dealing with mold in the home, and, despite the convincing commercials, powerful antibacterial sprays that target black mold simply aren’t worth the money.

The truth: bleach is an excellent disinfectant, and fantastic at making everything look sparkling clean. A whitening appearance means that all the dirt and nasty stuff has gone, right? But appearances can be deceiving.

A common misconception is that mold behaves similarly to bacteria. While both live in colonies and are classified separately from plants or animals – mold is part of the fungal family, and bacteria are single-celled microorganisms1. Mold plays an important role in aiding the decomposition of dead matter in the wild and can be found in humid wet places2. Meanwhile, bacteria can be found all over our planet, in soil and water, inside plants and animals.

Their behaviors are distinctive – mold reproduces by releasing spores into the air, while bacteria generally only release spores when there is no alternative: they usually reproduce asexually. In the same way that mold and its function is not inherently bad, different bacteria strains have different purposes in the soil, in water, and in your gut microbiome – and these are just a few examples. Both bacteria and mold are important to the ecosystem, and so cannot be dismissed out of hand as bad. But they are not the same thing, so it seems odd that we attempt to clean them up with the same cleaning products.

Bleach is an antibacterial product, often used for sterilization, normally with a chlorine base. Sodium hypochlorite is used in the production of liquid bleach. There are a handful of reasons that bleach is not the answer for cleaning mold:

Spores – Bleach is unable to kill off mold spores, which is their way of reproducing. Mold releases spores in order to create new colonies. Bleach can’t neutralize mold spores and mycotoxins, meaning they remain stuck to surfaces that are otherwise “sparkling clean”.

Porous Materials – Bleach is adequate for removing mold on non-porous materials such as work surfaces, sinks, hard plastic floors, tiles, and glass. However, on porous materials, bleach struggles to make an impact: killing the visible mold on surfaces such as wood, fabric, and drywall, but unable to reach the mold which remains underneath the surface ready to grow again3.

Available Mold Resources – Cellulose, the organic matter that feeds mold, can stop the bleach from fully sterilizing the area. Organic matter turns bleach inactive4.

Lack of Beneficial Bacteria – Bleach is an excellent antibacterial agent, but it works too well as a biocide, rendering places where it’s used completely sterile5. Not all bacteria are bad: some types of bacteria can do a lot of good, including the microbiome in your gut. Some bacteria in your home and in the wider world have the purpose of feasting on mold colonies. But if you kill off these friendly bacteria, you leave a vacuum where mold can flourish.

You may find it difficult to wrap your head around this information, after years of mopping, scrubbing, and spraying mold with bleach. Bleach may still have a purpose – though here at Homebiotic, we’d argue that a sterile home should be very low on your list of priorities. There are many more health benefits to encouraging friendly bacteria in your home.

Since using bleach is highly not recommended, what is a suitable alternative to not only kill mold spores but ensure your family remains protected from harmful chemicals? The good news is that mold only releases spores when it’s thriving, so your plan of action is simple:

  • Cut the mold off from its creature comforts: Reduce the moisture and condensation in your home, and get your leaky roof and rickety plumbing sorted out once and for all6.
  • Control the humidity in your home: Dehumidifier machines are great for this, but depending on the climate of where you live, simply cracking open the window can help.
  • Use a HEPA filter vacuum cleaner: Frequently suck up any dust and mold spores that may be hiding in the carpets and upholstery. Mold spores can lie dormant for years7.
  • For killing mold on porous surfaces, use borax (sodium borate): Wipe clean the surfaces using borax. Borax is not an antibacterial substance: instead, it changes the pH of the area you’re cleaning, making it inhospitable for mold.
  • Additionally, you can use Homebiotic Surface Cleaner: It cleans surfaces naturally without harsh chemicals that damage your home and body biome. The Homebiotic Nano Sponge wipes away mold, dirt, and grime without cultivating harmful bacteria found in conventional sponges. Following up with the Homebiotic Probiotic Spray will re-introduce good bacteria into your home environment, which helps fight grime before it causes a problem.
  • Stop using antibacterial products: The Homebiotic Probiotic Spray will reinstate friendly bacteria – to consume mold, and to protect the natural microbiome of your home.

Cleaning Mold: Bleach vs Hydrogen Peroxide

Cleaning Mold: Bleach vs Hydrogen Peroxide | cleaning mold with hydrogen peroxide or cleaning mold with bleach

Although minor mold spots are easy enough to wipe away while cleaning, the mold often returns quickly. While you might think to reach for the disinfectant spray or prepare a bucket of bleach to douse the area to kill it once and for all, these are not the best solutions for fixing a mold issue. These disinfectants are named for their ability to dis-infect, or kill, microbes and while that may sound good, in many cases this can actually make a mold problem worse!


If you look underneath the sink of an average home, you’re most likely going to find a variety of disinfectants, including bleach. Bleach is often a go-to remedy for stubborn stains and is used for making areas of the kitchen and bathroom sanitized and clean, but have you ever wondered why?

The most common kind of bleach is chlorine bleach, a water-based solution containing sodium hypochlorite as the active ingredient. Bleach removes stains from fabrics and non-porous surfaces by oxidizing and breaking down networks of double bonds between the carbon atoms making up the discoloration, removing the stain’s ability to absorb light. So the bleach doesn’t really neutralize and break down the matter creating the stain completely, just the bonds that make it visible to the human eye!


When you apply bleach to mold or mildew on tile grout, for example, it’s killing what’s on the surface and lightening the stain that the mold growth has caused, which makes it look as though it’s gone. But, that’s not the whole picture.

Bleach only works well on non-porous surfaces, and isn’t effective on porous surfaces such as wood, drywall or tile grout. While it may be effective at killing mold on the surface, the chlorine is unable to penetrate into the surface, so is either left on the surface or evaporates into the air of your home. Meanwhile, some of the water does seep into the surface and provides moisture to help the surviving mold grow back. And it does, more quickly each time it seems! If that wasn’t bad enough, you’ve now added harmful volatile organic compounds (VOCs) in your home as well.

Another reason to not use bleach to clean mold is even if the actively growing mold is killed, many of the health effects of mold are actually due to their byproducts, called mycotoxins, which bleach doesn’t affect. Bleach is also highly irritating to use, and should only be used with personal protective gear such as eye protection, a mask, and gloves, as well as good ventilation. For these reasons, we definitely recommend against using bleach to clean mold.


Hydrogen peroxide is often referred to as an oxygen bleach, because it acts as an oxidizer, chemically attacking the cell wall of bacteria, often rupturing it entirely. Regular 3% hydrogen peroxide is effective at killing surface mold, and only needs to be sprayed on and left for 10 minutes or until it stops fizzing. Repeat as necessary until the visible mold is gone, taking care to not over-wet the surface.

The Homebiotic Surface Cleaner is also an effective way to clean mold as it contains citric acid. Unlike conventional chemical cleaning products, that strip beneficial microbes from home surfaces, Homebiotic allows you to clean surfaces naturally without harsh chemicals that damage your home biome. Following up your cleaning with the Homebiotic Probiotic Spray will help you maintain a natural, safe balance of microbes on surfaces, which will protect your home and family against exposure to toxins that could negatively impact your health.


Regardless of what product is used to clean a surface, if the surface is left bare it will quickly be repopulated. If nothing is done, either sub-surface mold will grow back, or perhaps a harmful bacteria lurking in your kitchen or bathroom will move in.

The solution is to reintroduce friendly bacteria from healthy soil

These friendly bacteria naturally balance out these unwanted guests. When cleaning your home, and especially when cleaning mold growth, applying the Homebiotic Probiotic Spray  immediately afterwards will help keep these surfaces stay clean at a microscopic level. Homebiotic Probiotic Spray is colorless and scent-free, so you won’t even notice it’s there. It just forms a probiotic barrier for your home… naturally.
