What to Use to Clean Off Mold from Building Surfaces, Contents, Items
 Just below we answer some of the most common mold cleanup questions posed by our readers, followed by a detailed homeowner's guide to popular mold cleaners, mold removers, mold killers, and other mold cleanup approaches.
What to use to clean off mold from all of the exposed hard, cleanable surfaces: to clean off a moldy surface, you could use simple clean water, soapy water, spray cleaners, or if you prefer,
a commercial biocide (follow their directions) or a dilute bleach cleaning solution. But because so many readers have asked about specific mold "cleaning" or mold "killing" methods we list and comment on these approaches below.
- Water to clean mold: After discussing mold cleaning with an expert mycologist (J.H. NYS DOH), we agreed that simple water and a scrubby sponge work fine for cleaning off superficial mold.
- Soap and water to clean mold: using any household cleaner or soap solution, works well where we want to leave a nicer looking surface.
- Color of mold does not impact choice of mold cleaner: it does not matter what color or kind of mold you are cleaning up - in most cases the cleaning methods will be just the same.
- Type of surface being cleaned impacts mold cleaner choice: the type of moldy surface or material being cleaned up matters a lot. Hard surfaces such as wooden objects or wood framing are easy to clean with any cleaning product and a scrubby sponge, rags, paper towels. See MOLD CLEANUP - WOOD FRAMING & PLYWOOD.
- Hard surfaces that don't absorb water are easiest to clean: wipe the item in or with a solution of warm water and detergent.
- Washable items such as clothes, curtains: use your washing machine and laundry detergent. Clothing that cannot be laundered can be dry-cleaned.
- Dusty surfaces that are not actually holding mold growth can be vacuumed or cleaned using normal methods.
Irregular surfaces such as a roof deck penetrated by nails cannot be efficiently cleaned by hand-scrubbing, and media blasting may be needed. It is virtually impossible to effectively clean moldy carpeting or moldy upholstered couches.
Moldy insulation cannot be cleaned and must be replaced. See INSULATION MOLD.
- Carpeting (wall to wall), carpet padding, thick upholstered furniture, sofas, and similar items that have been exposed to wet moldy conditions cannot be effectively cleaned and are normally disposed-of. (Valuable antique furniture might be stripped and sent to be reupholstered.)
Don't spend more on cleaning an object than its replacement cost or value.
- Total area of moldy materials affects mold cleanup approach: large areas of mold, more than 30 sq.ft. need to be cleaned up by a professional; if you are tackling a small area of mold, or are hiring someone to do so, be sure that the cleanup stops, and a professional is consulted, if your demolition/cleaning procedure discovers a large area of mold that you had not seen before. See MOLD CLEANUP GUIDE- HOW TO GET RID OF MOLD.
- Cause of mold affects mold cleanup approach: while it may be reasonable to begin a mold cleanup project as soon as the mold problem is discovered (we do want to get rid of mold indoors), the cleanup job will be ineffective and possibly you'll be wasting the effort and expense if you don't identify and fix the cause of indoor mold contamination in the first place. Once you have identified and corrected the cause of mold in your building, you'll also want to take steps to prevent future mold growth. See MOLD PREVENTION GUIDE.

Readers should also see MOLD CLEANUP with BLEACH and MOLD CLEANUP - WOOD FRAMING & PLYWOOD and also MOLD CLEANUP MISTAKES to AVOID.

Guide to Popular Approaches to Cleaning up Mold in a building or on building contents.
Basic mold cleanup safety warning: If you are doing your own mold cleanup be sure to wear appropriate protective clothing, goggles, HEPA-rated respirator, better, a respirator that filters both fine particles (HEPA) AND that filters out the MVOCs (gases produced by mold), gloves, etc. If you are asthmatic, immune impaired, sick, elderly, or an infant, it would be smart to have an expert clean up your mold while you stay out of the moldy area or building.
The U.S. EPA recommends these mold cleanup safety tips [our comments are in brackets]
- Avoid breathing in mold or mold spores. In order to limit your exposure to airborne mold, you may want to wear an N-95 respirator, available at many hardware stores and from companies that advertise on the Internet. (They cost about $12 to $25.) Some N-95 respirators resemble a paper dust mask with a nozzle on the front, others are made primarily of plastic or rubber and have removable cartridges that trap most of the mold spores from entering. In order to be effective, the respirator or mask must fit properly, so carefully follow the instructions supplied with the respirator. Please note that the Occupational Safety and Health Administration (OSHA) requires that respirators fit properly (fit testing) when used in an occupational setting; consult OSHA for more information (800-321-OSHA or www.osha.gov).
- Wear gloves. Long gloves that extend to the middle of the forearm are recommended. When working with water and a mild detergent, ordinary household rubber gloves may be used. If you are using a disinfectant, a biocide such as chlorine bleach, or a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC (see Cleanup and Biocides). Avoid touching mold or moldy items with your bare hands. [Bleach makes people more comfortable about their mold cleanup job but except for cosmetic reasons such as removing stains, it is unnecessary in a mold cleanup project - see MOLD KILLING GUIDE and see MOLD CLEANUP with BLEACH.]
- Wear goggles. Goggles that do not have ventilation holes are recommended. Avoid getting mold or mold spores in your eyes. [We have had a few reported cases of actual loss of an eye by people who got moldy debris into an eye and failed to recognize and diagnose the problem until too late. But wearing goggles without vent holes, while safer, may mean that your goggles fog and you can't see. Don't let this mean you simply give up and take them off. Use anti-fogging goggle or eyeglass products.]
See MOLD CLEANUP GUIDE- HOW TO GET RID OF MOLD for details.
- Air purifiers for mold: portable indoor air purifiers are ineffective at correcting a mold problem in a building - just consider the mold reservoir in a mold contaminated home as an infinite particle source. The air "purifier" may pull some particles out of the air but it is no more effective at removing a mold problem than standing in the kitchen, waving your vacuum cleaner wand in the air, and expecting to pick up all of the dust from the nearby living room floor. An air purifier will indeed reduce the number of airborne particles if it is operated in a small-enough closed room, and that may improve occupant comfort, but air purifiers do not cure nor clean up nor remove an indoor toxic or allergenic mold problem.
- Air scrubbers or air sprays of fungicides and disinfectants: are popular among mold remediation companies who expect the mold clearance inspector to rely on an air test to "pass" the building after a mold cleanup job. (See MOLD CLEARANCE: FOLLOWUP STEPS for a discussion of mold clearance inspections.)
Their proponents argue that these products "knock down" airborne mold in the building - a reasonable view considering that demolition and cleaning of moldy building surfaces can stir up high levels of airborne mold. A similar "cleaning" of the air inside a building after mold remediation may be attempted by "fogging" with a fungicidal sealant paint (also effective, and also risky - see FUNGICIDAL SPRAY & SEALANT USE GUIDE and our comments on fungicidal sprays just below).
The mold remediator who has constructed a contained, sealed area does not want to be blamed for airborne mold entering the building from other areas that were not treated. This makes sense if the building was not fully and competently inspected in the first place, as other problem mold reservoirs outside the remediation area may be present.
But in most locations, simply ventilating the building with fresh air after cleanup can produce the same results.
Beware: if the moldy materials were not adequately removed, if moldy surfaces or debris were left in the work area, no amount of air sprays, surface sprays, or air scrubbing using a HEPA-filtered air handler, will correct the indoor mold problem any more than you can pick up dust from a living room floor by standing in the kitchen and waving your vacuum cleaner wand in the air. Our photo (above left) shows a horrible "professional mold remediation job" in which the cleaning company left moldy insulation and debris in the crawl space. The contractor simply stood at the crawl space entry and sprayed in some fungicidal paint.
- Bleach to clean mold:
Be sure to read MOLD CLEANUP with BLEACH and MOLD CLEANUP - WOOD FRAMING & PLYWOOD and also MOLD CLEANUP - MISTAKES to AVOID. Also see see TRAPPED MOLD BETWEEN WOOD SURFACES for a discussion of the question of need to remove mold from mated, inaccessible building surfaces such as between the top of a floor joist and the under-side of subflooring.
Once you've read about bleach it will be clear that any cleaning method that removes surface mold is fine: water, soap and water, household cleaners. Stains that are left behind, such as on framing lumber, are generally harmless (fungal hyphae left in the actual wood), provided that you keep the building properly dry. And if you don't keep the building properly dry, new mold growth will readily occur on many surfaces regardless of the old stains that were left from the prior mold cleanup.
- Carpet cleaning to remove mold from wet moldy carpeting is not effective regardless of method used (dry chemical, steam, wet scrubbing). Dusting carpets with baking soda is also ineffective at removing problem mold, though it might make the carpeting smell better for a while.
Steam cleaning moldy carpets will neither kill nor remove enough mold in the carpeting nor in carpet padding to make such materials salvageable if the carpet was wet and/or harboring actual mold growth.
Vacuuming a carpet exposed to moldy dust (say from other building areas) is fine. Vacuuming will not effectively clean a carpet that has been wet or has harbored mold growth.
Wet moldy carpeting is generally discarded as is wet moldy carpet padding or carpet padding that was below wet moldy carpets.
- Caulk over mold? Don't caulk over moldy caulk such as in a bathroom or around a window. Even "mildew resistant" caulks are not proof against ultimate mold re growth in the new caulk, and you have not removed the problem. Cut and strip away moldy caulk, clean the exposed surfaces, be sure there is no leak behind the area to be caulked, then re-caulk with a mold resistant caulk (often sold under the incorrect name as "mildew resistant caulk".
- Clothes washing and dry cleaning to remove mold from clothing, bedding, even curtains, is generally very effective for these soft goods. Upholstered furniture, pillows, mattresses that have been wet and moldy are generally discarded as surface cleaning by any method (even steam) is unable to remove mold from deeper in the material.
- Deck Cleaner Solution vs. Media Blasting to clean mold: For cosmetic reasons we might use a more aggressive cleaner or even bleach, but that's for appearance, not because we're trying to "kill" mold. For example, where cleaning an indoor surface where wood is left exposed for cosmetic or aesthetic reasons, we may use MOLD CLEANUP by MEDIA BLASTING or we may use a deck cleaner solution (intended for outdoor use). The down side of any indoor cleaning that uses a water-based spray in quantity is having to deal with the water itself - dumping more water into a moldy building invites more mold problems. So wet methods work better outdoors or over a concrete floor that can be quickly cleaned and dried.
- Detergents to clean moldy surfaces: household cleaning detergents are just fine, liquid or powder are equally effective and involve less suds to be cleaned off.
- Dehumidifiers for mold: a dehumidifier will not clean up nor correct an existing mold problem, and temporarily, when you drop the humidity in a damp moldy area, the level of airborne mold will actually increase (the drying mold decides to release its airborne spores to find a better home). A dehumidifier is an important part of mold prevention, however. See MOLD PREVENTION GUIDE and see HUMIDITY CONTROL TO PREVENT MOLD. Also see DEW POINT TABLE - CONDENSATION POINT GUIDE for an explanation of dew points and indoor humidity in buildings, and see MOISTURE PROBLEMS: CAUSE & CURE and HOUSEWRAP AIR & VAPOR BARRIERS and VENTILATION in BUILDINGS.
- Dishwasher to remove mold: a dishwasher is effective for removing mold from most dishware and glassware; on occasion we find mold stains that have developed below cracked glazing on antique dishware, and we've had some success in correcting this cosmetic problem using bleach (below).
- Enzymes or fungicides to clean mold: while these products can produce nice looking results, and while their claim of "killing" all mold (an exaggeration in many cases), are not relevant to a proper mold cleanup (where removal is the key word), their use is not generally necessary. Read CLEANUP with BLEACH for a more complete explanation of the difference between "killing" mold and "removing" mold.
- Fungicidal sprays to "clean" mold: can be an effective surface cleaning method, but much too often we find that the mold "expert" rushes the job, relying on the spray to "kill" or "immobilize" mold without first finding and removing the mold actual problem mold reservoir. Sprays are not an effective substitute for actually cleaning or removing problem mold. See these articles:
FUNGICIDAL SPRAY & SEALANT USE GUIDE
FUNGICIDAL SPRAY ADVANTAGES
MOLD SPRAY WARNINGS
MOLD SPRAYS, SEALANTS, PAINTS - sources, choices, suppliers
Our photo (left) shows small particles that were immobilized in airborne droplets of a clear fungicidal sealant spray.
- HEPA Vacuum Cleaning to remove mold: a HEPA-rated vacuum cleaner is used during dry surface cleaning methods to reduce airborne moldy dust and also to clean up moldy dust and debris from building surfaces. Don't use an ordinary household vacuum cleaner or "shop vac" that is not HEPA rated or you will simply increase the level of airborne mold in the building. For an effective reduction of indoor dust levels and moldy dust levels in building areas outside of the mold remediation area, where no mold growth contamination was present, HEPA vacuuming is often recommended as a final step in complete building cleaning.
- Laundry soap to clean or remove mold: laundry soap is effective as a household cleaner but may be more concentrated than you need; we use laundry soap and two washings to clean up moldy washable goods like towels, clothing. Sometimes mold leaves a stain on soft goods and bleaching may be needed for cosmetic reasons.
- Media blasting to remove mold (see MOLD CLEANUP by MEDIA BLASTING for details) as we mention above, is useful for cleaning wood surfaces to be left exposed (for cosmetic reasons) or where the moldy surface is very irregular (such as a roof deck with protruding nails), preventing normal surface scrubbing methods.
- Mildew removers and mildewcides to clean or remove mold: a mycologist will tell you that mildew does not grow in buildings - just on living plants. Mildewcides intended for plants should be restricted to that use. "Mildewcides" sold for indoor use as a "mildew remover" or "mildew cleaner" are mold cleaning products - see Mold soaps and mold killing cleaners below.
- Mold soaps and mold killing cleaners: special cleaners sold to clean up or remove mold may be fine, but they are not more effective than using household cleaners in cleaning a moldy surface. Some cleaners that contain a biocide and report that they will kill the mold are appealing to consumer fear, but are unnecessary. See MOLD CLEANUP MISTAKES to AVOID and see MOLD KILLING GUIDE.
- Mold test kits to check for mold cleanup effectiveness: we agree that testing for the effectiveness of mold cleanup and testing for cross contamination by moldy dust between the cleanup area and other building areas is appropriate when a costly or large-scale mold remediation job is to be performed. Tests should be done by an expert who has no relationship with the mold cleaning company. Beware of mold test kits that rely on cultures (they are inaccurate - see MOLD CULTURES) and beware of amateur mold sampling that may collect screening samples from the wrong place.
- Natural or organic mold killers, organic mold cleaners, green mold removal products: these cleaners are fine to use to clean up mold, and are preferred by people who want to avoid more harsh chemicals. As our object is to remove mold leaving a clean surface, even simple water and a scrubby sponge could be used to clean a moldy surface.
- Ozone to "remove" or "kill" mold or odors is a mistake in a moldy building. One of the most ridiculous magic bullet mold fixes we have seen is a costly "tenting" of the entire building so that the structure and its contents could be "sterilized" using ozone. This magic bullet has been so abused in the mold industry that it has been specifically "not recommended" by the US EPA and other expert sources. See these articles for details:

- Paint over mold? Don't simply paint over mold with a "mold paint" or "mildewcide paint" - these steps are ineffective, mold usually grows back through the paint, and you have not removed the problem.
- Steam cleaning to remove mold: steam cleaning can be effective in cleaning thin cloth covered surfaces but it does not penetrate sufficiently to clean a moldy couch or carpet. Remember too that our object is not to kill mold (which some steam cleaners claim and which is inaccurate and ineffective anyway). Our cleaning object is to remove the mold. Steam cleaners may claim to "destroy the mold" but in nearly twenty years of testing moldy upholstered furniture and carpets before and after they were "steam cleaned" for mold we have not found a single case where this was effective. The steam does not penetrate fully through thick upholstered materials and even a very powerful commercial vacuum cleaner cannot pull enough mold and similar small particles from the center of an upholstered couch cushion nor a carpet to leave those products mold free.
- Vacuuming to clean up mold: we recommend using HEPA vacuum cleaners to clean up moldy dust or general dust in buildings after a mold cleanup job, but not to clean surfaces where mold is growing. Don't use an ordinary non-HEPA rated vacuum cleaner or you'll just be aerating the mold and other small dust particles. Don't try to clean a surface where mold is growing by just vacuuming - it's unlikely that vacuuming will remove enough of the mold growth that is adhered to the surface.
- Vinegar to get rid of mold: because it is a mild acid, vinegar makes a good household cleaner for many surfaces. Don't choose vinegar because you think your object is to "kill the mold" - that's not the correct objective. See MOLD KILLING GUIDE.
We have no financial interest in any of these products. This data was discovered by internet search. We have no
scientific data as yet regarding the effectiveness, toxicity, chemical composition, nor durability of these products. We do not recommend using thick plaster or cementious coatings as these are more likely to later crack or leak, trapping
moisture inside against the wood and promoting worse mold growth.
How to Use Bleach to Clean Up a Moldy Surface
Bleaching or "killing" mold is not the objective. Bleach will not kill all of the mold anyway - we can tease viable spores out of lots of "bleached mold" samples we see in the lab.
The object of mold removal is to clean the surface, to remove loose moldy material, not to try to sterilize the surface. Certain mold-contaminated materials that cannot be cleaned (drywall, carpeting, curtains) should be discarded. Clothing and bedding linens or towels can be washed or dry-cleaned.
Keep that in mind. If you want to use bleach as a cleaning agent instead of other cleaners (soap and water would work just fine) here are some mold cleanup suggestions for homeowners from the Canadian Mortgage and Housing Corporation CMHC. Please see BLEACHING MOLD, Advice about for details of how to mix and use bleach to clean a hard surface in a building as well as warnings about where bleaching mold is a cosmetic band-aid that just won't work.
- Dilute bleach with one part household bleach to four parts of clean water (do not add other cleaners to this solution as you may accidentally cause the release dangerous chlorine gas)
- Ventilate the work area
- Wear rubber gloves and eye protection
- After physically cleaning and removing all loose mold, dirt, debris, from the surface being cleaned, let the solution stand on the surface for 10-15 minutes.
- Rinse the cleaned surface thoroughly
- Be sure that the cleaned surfaces are totally dry before restoring any building insulation, drywall, etc.
- Discard moldy fabrics or other similar materials that cannot be surface-cleaned.

OTHER IAQ ISSUES: How To Find and Address Other Indoor Air or Indoor Environment Contaminants Besides Mold
Mold or allergens may not be the only or even the main indoor environmental contaminant. Don't let media attention to mold
cause so much enviro-scare fear that other, possibly more urgent hazards go un-addressed.
- Fiberglass building insulation and HVAC duct work insulation hazards
- Sewage and Septic backup contamination in buildings: inspection, testing, remediation, & references to expert sources
- Other environmental risks: Asbestos, carbon monoxide,
electromagnetic fields, environmental illness, fiberglass, MCS - multiple chemical sensitivity, toxic gases, etc
- Indoor Gas Sampling Plan
for Residential Buildings lists a number of toxic indoor gases which we test for, depending on the building
complaint and building conditions
- Ozone Warnings - Use of Ozone as a "mold"
remedy is ineffective and may be dangerous.
- Pet control - if you can't say goodbye to your bird, cat, dog, guinea pig, hamster, tropical fish, then limit the
areas they occupy and limit the airflow from that area to sleeping or other areas of the building, use allergenic
bedding, eliminate wall-to-wall carpeting, improve housecleaning including use of a HEPA-rated vacuum cleaner. For more details
see our article Dog, Cat, and Other Animal Dander - Information for Asthmatics and Indoor Air Quality
- Rodents, Mice, Squirrel Control - I find high levels of mouse and rodent dander, fecal dust, and urine-contaminated dust in some buildings,
and high levels of these materials in building insulation in those locations. If you have a mouse problem, particularly if mice and their waste (fecals or urine) are contaminating
the building HVAC or building insulation, may need both steps to clean up or remove infected materials and steps to stop an ongoing
rodent problem. If squirrels are a problem, the cleanup needs to include closing off entry openings into the building. Get some
help from a licensed pest control expert.
