Mold illness can be sneaky and symptoms may seemingly come from nowhere. Mold illness symptoms can range from low level and feel like a bout of flu you can’t shake to debilitating fatigue that makes getting through the day tough.
When you Google for more information, all you find are dramatic photographs of black mold – something you just don’t see in your home. It’s important to know that not all mold can be seen by the human eye.
Let’s look at ways to clean up harmful mold and reduce its impact on your life.
Targeting the Underlying Cause of Mold
Mold thrives in moist and warm conditions. When these conditions combine with a suitable food source, mold can spread very quickly, often in unseen places. Mold easily lives on paper, cardboard, wood, fabric, carpet, drywall, and many other common building materials.1
The underlying causes of mold include:
- Moisture: Ensure any water pipe or roof leaks are fixed. If the property has a history of flooding, you need to evaluate the risk of it happening again and maybe even consider a house move. Extensive flooding increases the risk of mold contamination.2 I recommend removing wet carpet from your property as soon as possible, as they encourage not only the growth of mold, but also bacteria.3
- Holes and gaps in the walls: Look out for cracks in walls or windows – they may be letting mold in through your external walls.4
- Condensation: If the warm air inside your property hits a colder surface, like your windows, it causes interior condensation. This often leads to mold eating away at wooden window frames. To specifically target your windowsills, moisture eliminator products are useful. However, if you suspect mold elsewhere in your house, they won’t be effective.
- Air Conditioning units: Your air conditioning, heating, and ventilation unit needs regular maintenance and cleaning to ensure that it is not the culprit. It could be circulating fungus spores around the house. Get an expert to look into it and consider getting a HEPA air scrubber to clean the air.
- Humidity: I advise you purchase one or more dehumidifier units, depending on the size of your home. A dehumidifier ensures you can keep the humidity of your property around the 50% mark – mold finds it harder to multiply in drier air.5
If this list seems intimidating, bear in mind you can hire a remediation company to assess, contain, and remove the mold. Make sure you pick a company certified in mold remediation.
How to Get Mold Out of Carpet
Mold loves fabric, making most furniture a potential hub for mold. If you are cleaning up after a large leak, I recommend removing the carpet completely. In mold infestation cases where the carpet has not gotten wet, it’s a good idea to buy a high efficiency particulate arrestance (HEPA) vacuum cleaner to clean your carpet.
You must choose a true HEPA vacuum cleaner, not one that is labeled ‘HEPA like.’ HEPA vacuum cleaners utilize a strong motor and fine filter to suck up everything, including mold spores, whereas regular vacuum cleaners suck up the mold spores – only to deposit them back into the air.
When using your true HEPA vacuum cleaner:
- Make sure you vacuum from every angle. When vacuuming it’s easy to get into the habit of pushing the machine across your carpet in the same direction. Many modern vacuum cleaners have a more flexible design, meant to get into difficult corners or underneath furniture. Use it from every direction possible to remove as many mold spores as possible.
- Empty your vacuum cleaner outside. If your vacuum model is bagless, use a disposable wipe to clean out the canister fully. Avoid breathing in the dust by wearing a N-95 respirator.6 If your vacuum cleaner uses bags, ensure you wear protective gloves, respirator, and clothing as you do so to avoid carrying the spores back into your home.
- As the dirt, dust and mold spores in the fibers may have been accumulating for years, don’t be disheartened if you don’t see an immediate improvement in the state of the carpet or your health. It may take several long sessions of vacuuming before you start to feel the benefits.
How to Get Mold Out of Clothes and Soft Furnishings
Mold removal is not straightforward when it comes to soft furnishings and clothes. If you use biocides such as diluted bleach and vinegar, the mold on the fabric dies, but the mycotoxins continue to be an allergen. It is not enough to kill the mold, it needs to be completely removed.
Also, using harsh chemicals such as bleach on fabrics is hardly ideal. Unfortunately, wiping upholstery doesn’t remove the mold from the stuffing inside. And dry cleaning can cause cross contamination from other sources.7
Instead, I recommend borax, also known as sodium borate which is a mineral and a completely natural solution for cleaning mold. Borax also combats bacteria.
Pre-soak your laundry for 30 minutes in a solution of one tablespoon of borax per gallon of warm water or add 1/2 cup of borax to a pre-soak cycle. The alkaline pH of borax helps to break down acidic stains, such as tomato or mustard.
Borax works well on mold because it’s alkaline, making an inhospitable place for the mold, which prefers a lower pH environment. You must take care when using it – always wash your hands after handling clothes that have been treated with it and avoid getting it in your mouth or eyes.
How To Get Mold Out of Your Wooden Furniture, Walls, and Other Surfaces
Mold loves hard surfaces, especially wood or plaster. Luckily, borax is suitable for most furniture.
Be wary of the claims made by most household cleaners – just because a surface is sparkling and clean looking, it’s no indication of how many mold spores are still stuck to it. I recommend the following procedure for a surface that may have been contaminated:
- Use two rounds of disposable wipes to clean the surface.
- Move on to using a dry microfiber cloth to wipe up any excess moisture and mold spores.
- Throw the disposable wipes in the garbage – being careful to avoid cross-contamination of your clothes.
- The microfiber cloths can be washed on a hot wash cycle and reused. They are also more effective for everyday cleaning, wet or dry.
Of course, some surfaces are more of a challenge to clean. Mold spores stick easily to surfaces in the kitchen that tend to be coated in grease or cooking oil. I recommend that you cut through the grease with a simple soap or detergent, before using borax or the wet and dry cloth method.
How To Get Mold Out of Your Prized Possessions
If you or a loved one have been diagnosed with a mold related illness, your doctor may have suggested you remove all items likely to be contaminanted – including most of your possessions. While your doctor is interested in your wellbeing, the thought of removing all your favorite things may feel unbearable. There is also no guarantee that all of your possessions contain mold or mold spores. So it’s important to make well informed choices.
Possessions you can clean and keep:
- Non-porous items, e.g metals, glass
- Jewelry
- Pottery
- Glassware
- Plates and dishes
- Cutlery
- Leather
- Decorations
- Framed artwork (remove from frame, dust and reframe)
Possessions that require more thought:
- Paper
- Paperwork & important documents
- Books
- Photos
- Old letters
- Yearbooks
Books and paperwork are hard to clean adequately and book conservationists recommend wearing protective clothing and masks when handling mold-damaged books.8 It may be time for you to go digital. Photos, old letters, and yearbooks can also be digitalized, saving you from heartache.
- Rugs and furnishings
- Antique rugs
- Bed, mattress, pillows, bedding
- Taxidermy
- Indoor plants
- Holiday decorations
You need to replace your bed completely, as it is the only way to make sure you’re not exposed to mold in your sleep. Indoor plants and taxidermy are prime sources for mildew. Antique rugs are just as bad as carpet for attracting mold and are harder to clean.
- Non-washable clothes and accessories
- Shoes
- Bags
- Dry clean only items
- Non-waterproof watches
- Toys
- Stuffed animals
- Plastic toys that are difficult to clean adequately
Whether it’s your childhood bear or a recent addition to your childs collection of toys, it is unlikely that a spin in the washer removes mold spores or toxins.
- Home Appliances & Electricals
- Refrigerator
- Washer and dryer
- Air conditioner or purifier
- Home computer or laptop
- Televisions and stereos
Washers and dryers are often a source of cross contamination, as mold can grow inside the drum. It is difficult to clean the back of refrigerators properly. Modern electronics are hard to clean inside and a compromised computer often blows out mold spores whenever the fan starts up. An air conditioner or purifier can also cause contamination when brought into a clean environment.
- Open Consumables
- Open food packets
- Jars of rice, flour, spices etc
- Open cosmetics and toiletries
Whatever you decide, you’ll need to clean and store many of your possessions in sealed boxes in a place external location from your home while you work on your mold issue. It’s possible that you will need a few months to sort through your possessions.
How To Avoid Mold Cross-Contamination
I touched upon cross-contamination in relation to removing personal items, but there are many ways you can avoid contaminating your home once you have removed the mold. Some of these actions may seem extreme, but it’s the only way to ensure that your mold illness doesn’t come back.
- Reintroduce cleaned possessions into your home slowly, over a period of months, to ensure that each item is mold free.
- Domestic dogs or cats need to be boarded elsewhere. They need to be washed fully with an antifungal shampoo and shaved before they can return to the household.
- When cleaning possessions, surfaces, or removing the contents of your vacuum cleaner, do so outside, wearing protective gloves, a N-95 respirator and protective clothing. Never walk into your property wearing this protection, as it could cause cross-contamination.
- Wrap everything you intend to remove from your home in plastic bags – doubled up.
- If you suspect a second source of mold contamination (ie. your office) you can use a mold spray such as Concrobium or EC3 Mold Solution on your clothes and everyday belongings to avoid cross contamination.
- Remember that certain items can survive mold spray decontamination better than others – avoid bringing papers, books, used computers, and soft furnishings that may already be compromised into the house.
Above all, though it can be tempting to make a number of huge changes all at once, I recommend consulting a functional medicine doctor that specializes in mold illness and taking action a little at a time. I hope this helps you know exactly what to do in the case of mold.

Dr. Carnahan,
Can you share your thoughts on stool DNA testing such as Viome? If your gut can change quickly based on diet and external factors, would the recommended diet plan still work? Do you think tests like Doctor’s Data are more viable?
Thank you!
Viome is cutting edge and interesting but still not useful in clinical practice. For DNA PCR, I use GI MAP for testing and treatment
I’ve greatly appreciated the information I’ve run into from you from various sources. Thank you! I was diagnosed with CIRS 2 years ago. We are thinking of moving from the Nashville TN area to Colorado because I seem to have troible with outdoor mold here (can that even be a thing?). I have family in both Colorado Springs and Ft. Collins, do you think there’s a difference between the two? I think there’s more irrigation in Weld Co., would that have an effect? #farmgirltoo
Hi Kathy,
I really think it depends on the specific homes and buildings. I know no difference between Ft. Collins and CO Springs although Boulder was hit hard by a flood in 2013.
Warmly
Dr Jill
I would think that shaving pets would be pretty useless (and dangerous, harmful and cruel to pets) since the minute they go outside, they are going to pick up mold again and bring it back in the house. If people are really concerned about their pets contaminating the home, it would be more useful and to have them re-home or temporarily remove their pets until they are less sensitive. Sorry, but recommending shaving pets is unreasonable and wouldn’t work as even a short term solution.
Agreed but I have sadly seen too many DEAD pets from mold… much better to shave your pet than allow the toxic mold to cause harm. It is quite a bit more humane.
Thank you for this great guide. I was recently tested for mycotoxins by RealTime Lab. My results came back undetectable except for an equivocal value for gliotoxins. (.52 where .50 – 1.0 is equivocal). I am uncertain as to whether this would be indicative of mold illness? My house HERTSMI value is 12, in the borderline range. I have late stage Lyme, so it is very difficult to disentangle symptoms. Thank you for your consideration.
It is hard to tell with one result and gliotoxin may come from candida not mold so best to see a doctor who could help you with additional testing…
What certification should a mold remediator have?
Unfortunately there is no standard in the industry but you might try http://www.iaqa.org
Thank you for these broken down practical steps. I’ve been diagnosed with ME and it has gone from moderate to severe the past three years especially after living in monsoon prone countries. I am highly allergic to mold and dust mites according to my immunologists prick test. I used to have terrible hives, allergies and fatigue as a child. Now I am 90% housebound with severe physical and neuro immune exhaustion. As an Ayurveda therapist I’ve pursued so many routes to healing and detox but I’m floored now and financially strained from inability to work. I am hoping implementing these bit by bit will give me back some quality of life. I also wonder if fecal transplant therapy might help someone’s immune and biome adjust to handle these toxins more efficiently from a ‘healthy’ person?
Do you mind if I quote a few of your articles ass long as I provide credit and sources back to your site?
My blog site is in the very same area of interest as yours
and myy users would really benefit from a lot of the information you provvide here.
Please let mme know if this okay with you. Thanks a lot!
Yes, that is fine, just please link back to my site for each article you use
Hi Jill,
Is foxing on books a form of mold?
Thanks, Amber
foxing is not well understood but mold is one possibly explanation
Hi,
You mention under the cross contamination section to spray clothes with concrobium. Can you elaborate on what that would look like?
So when I leave work I would have a bottle ready in my car to spray myself down while still wearing the clothes? Would that be safe to do? What about my car? Since the cross-contamination already happened should I spray down my office as well?
I am just trying to get a picture of what my routine will look like.
Thanks!
If I replace my mattress won’t the new one just get contaminated?
not if you are in a clean environment… you must be out of exposure first
I noticed in one of your mold articles on our homes’ microbiomes that you recommend houseplants to purify the air but in this article you say not to have houseplants as they’re a source of mildew. I live in a home with a mold problem and I have valuable houseplants. When I move, if I wash the old soil away and buy new pots, rinse the plants and repot with fresh soil, should they be okay in my new home and not a source of cross-contamination?
Here’s some great tips https://herbsathome.co/how-to-remove-mold-on-houseplants/
What are your thoughts on plastics? Some things I read they are able to be cleaned, but others believe that mycotoxins are hard to wash from plastics. I have a kitchen of glass bowls and containers without lids, after washing everything. I have the washed lids in a bin of things I don’t know what to do with, along with other plastics like a small food processor.
I getting rid of as much plastic as possible and trying to sterilize your food processor
I would love an opinion on this – 3 years ago I moved from a mould-contaminated cottage that made me very unwell, into a new studio flat. Back then I didn’t know that the mould had made me sick, so brought all my (contaminated) possessions with me. My health is slowly improving due to herbal/dietary protocols, but should I throw out all my stuff or is it too late – have I contaminated my new place already, are the spores in the walls etc now?
Really grateful for any thoughts 🙏 💟
If you are feeling better and improving you do not need to through out all of your possessions.
Dr. Carnahan,
Can you expound on why computers are hard to clean? I’m trying to make the case to my employer that they need to send me new equipment. Can you cite specific academic sources that I can share with my functional medicine doctor? Thank you so much.
Hi Dr Jill!
3 things:
I need stark clarity on what we mean by cross contaminate and the threshold of bringing non porous objects cleaned into the new home like my beloved $800 air filter.
– Are we saying we are removing the objects bc we need to not be exposed to heal or bc it will make the new clean place just as toxic as the former? I cannot see anything in my condo for mold i am just ill in multiple ways and working with a functional doctor.
My computer and tv are flat and all in ones. There isn’t a fan that blows all the time like older models – Is this ok?
3- Can i borax my shoes? Shoes are hard to replace.
4- Electric guitars and amps – dump the fabric covers and vacuum/wipe the outsides?
5- My new IQAir filter I got maybe three months ago – this goes back to my original concern – change the filters, vacuum and wipe down? Are we chucking this away for the body’s sake or are we chucking it bc it will ruin a clean emvironment in a catastrophic way???
Hi Lindsey -Air filters may be wiped down but the filter inside needs to be replaced. We are only recommending removing objects that have a high risk of being contaminated by mycotoxins. If you can put your shoes in washing machine with dilute borax, soak and wash, they are fine to keep. I recommend trying to clean fabric covers with Surface Guard or similar solution if possible. You would need to clean and hepa vacuum and be sure you are no longer reacting to the material.
We got super duper CNS sick from Concrobium in our test/trial spots of carpet and a desk. Our symptoms match the warnings on the MSDS sheet for the aerosolized version. We have MCAS and MCS like many moldies. Please re-consider your recommendation for that product. e.g., headache & brain fog w/o mold reactions of skin symptoms, AND only when near the test areas…vision problems and left side of face dropping. (vision and dropping resolved when away from test areas)
Hi there!
Trying to wrap my mind around this – some mild mold was found in my bathroom and I tested positive for mycotoxins. I showed signs of CIRS.
I moved out of my apartment before I knew anything about cleaning contaminated items and have been feeling steadily better. Is it necessary to clean everything?
If so:
– Can I clean vegan leather shoes with EC3 or a borax soak? (summer sandals, leather sandals and boots)
– Do I need to wear PPE to wash my clothing? And how do I wash myself properly after handling potentially contaminated items?
Hi Sarah
You should be able to wipe down leather or vegan leather shoes as long as the mold cleaner is leather-safe. Ideally clothing could be handled with PPE but I have never seen this to be necessary as long as you change clothes and shower after handling moldy materials. I would base the precautions more on severity of physical symptoms or reactions to the materials. I use ZeoBind Plus and hydration after exposure to recover more quickly if you do feel poorly while handling the mold-contaminated materials
warmly
Dr. Jill
hello,
What can I use to remove mold from surfaces like tiles?
I use a product called Surface Guard HERE
