How to Clean or Remove Toxic Mold in buildings - A Homeowner's or Apartment Owner's Guide
InspectAPedia®  -      

  • Here is a step by step guide on what to do about mold in a building
  • How to clean or remove mold properly
  • Mold clearance inspections after cleanup
  • Questions & answers about the best procedures to get rid of mold and mold smells in buildings

This article describes how toxic or allergenic mold is removed from buildings - mold cleanup, or mold remediation. We discuss how to physically remove problem mold (don't just spray over it), what cleaners can be used for mold removal, and use of bleach in mold cleanup and removal jobs.

InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers nor with topics or services discussed at this website.

We also list related mold cleanup or remediation articles that address special problems such as mold odors, mold removal from irregular surfaces, and stains or odors on roofs or in cars. This is article is part of our series starting at ACTION GUIDE - WHAT TO DO ABOUT INDOOR MOLD, a document which provides an easy to understand step-by-step guide for dealing with toxic or allergenic indoor mold and other indoor contaminants: what to do about mold.

The steps in this document will be sufficient for many building owners who want to do their own mold investigation, mold testing, mold cleanup, and mold prevention in their home or office. Readers should also see 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 and inaccessible building surfaces.

HOW TO CLEAN MOLD: How to Clean or Remove Mold, Moldy Debris, Other Indoor Environmental Contaminants - a Homeowner's Guide

Please see ACTION GUIDE - WHAT TO DO ABOUT INDOOR MOLD for a detailed procedure on mold cleanup in buildings. What follows below is a succinct guide to mold cleanup for homeowners or tenants. Renters may also want to see RENTERS & TENANTS GUIDE TO MOLD .

Protect the occupants and yourself from mold, demolition dust, debris, cleaning chemicals, etc. Where a large area of cleanup is involved (more than 30 sq.ft.) a professional is usually called to establish negative air in the work area and to install containment barriers of plastic or other material to protect cleaner areas of the building from cross-contamination during the cleanup.

If you used a building environmental specialist to inspect and define the scope of work, you should have baseline mold test samples of both the work area and other building areas which will permit you to state definitively, at the end of the cleanup, whether or not the cleanup has caused cross-contamination of other building areas.

The spotless cleaning produced for the second photo above was obtained by using a professional who used media blasting to clean these surfaces. Such measures may be needed for large or complex surfaces, but quite often the necessary steps are less technical and less onerous, as we describe next.

Clean or remove mold and moldy debris: The most succinct Mold Remediation or Mold Cleanup Guidelines one could state would be this: the objective is not to sterilize your environment or "kill" mold, steps which are ineffective anyway - the operative words are "clean" or "remove" problem mold and then to correct its cause.

If the total square feet of moldy material is less than 30 sq.ft. it is reasonable to handle the mold cleanup as an ordinary building cleaning or renovation procedure - hiring experts to establish negative air, dust containment, etc. is not required, but you should still take steps to minimize cross contamination in the building and to protect yourself and other occupants from moldy dust and debris.

If the total contiguous square feet of moldy material is large (more than 30 sq.ft.) then you should consult a professional to inspect the building, find all of the problem mold areas, and to prepare a mold cleanup or mold remediation plan which will guide the mold remediation company (who should be a totally independent contractor in order to avoid conflicts of interest).

The mold consultant should also advise on the steps needed to prevent future mold growth - fix the causes of mold contamination. If the mold cleanup is a costly project you should have the independent mold consultant perform a thorough visual and physical inspection of the building after the mold cleanup to assure that it was effective.

Note: some sources have amended the 30 square feet rule to 10 square feet as the size suitable for homeowner cleanup.

Remove and dispose of moldy items that cannot be effectively cleaned: Moldy drywall, paneling, trim, carpets, boxes, junk, are removed and disposed-of as construction debris or trash, either because the item cannot be effectively cleaned, or in some cases because the cost of cleaning exceeds the value of the object. Be sure to remove building insulation that has been wet or smells moldy or has been exposed to high levels of airborne mold. See INSULATION MOLD.

Usually moldy drywall and other debris can be disposed-of as ordinary construction debris or trash.

Scrubbing moldy surfaces - no sprays, no ozone, no sterilization: We're talking about scrubbing here. It's the physical removal of moldy or allergenic debris that's important, not the surface sterilization. The second we permit someone to "spray for mold" we can count on them to fail to do an adequate mold cleanup.

And if the moldy surface to be cleaned is "cleanable" so irregular or inaccessible as to make physical wiping or scrubbing impractical, you may want to consider MEDIA BLASTING for MOLD REMOVAL. The photos at the top of this page show the results of media blasting moldy wood surfaces.

What to Use to Clean Off Mold from Building Surfaces, Contents, Items

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.

At MOLD CLEANERS - WHAT TO USE we provide a detailed description of different methods people use to "clean off" or "kill" mold.

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 MOLD CLEANUP with BLEACH 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.

How to Deal With Other Mold-Related Problems

  • CAR SMELL - Mold DEODORIZING - mold in cars, campers, trucks, RVs can be caused by water leaks and can make a moldy smell problem that's hard to cure.
  • MEDIA BLASTING for MOLD REMOVAL - for very irregular surfaces, physical cleaning of mold can be cost-prohibitive; try media blasting
  • MOLD CLEANUP - MISTAKES to AVOID
  • MOLD PREVENTION GUIDE - make sure that your mold cleanup effort is not wasted by taking steps to prevent mold growth recurrence
  • ODOR DIAGNOSIS CHECKLIST - maybe that smell isn't mold?
  • ODORS, Smells, Gases in buildings-Diagnosis & Cure - how do we track down mold or other building smells to their source - necessary steps to correct odors in buildings.
  • OZONE for MOLD OR ODORS - warnings about using ozone treatments to try to "kill mold" or "remove odors" - there is a place for this equipment but not as a substitute for mold cleanup and overdone it creates more problems than it solves.
  • STAINS on buildings - QUICK GUIDE - some indoor stains like thermal tracking are often mistaken for "toxic black mold"
  • STAINS on ROOF SHINGLES - those black roof stains might be mold, but more often, algae or something else
  • WATER ENTRY in buildings - not much use in cleaning up mold contamination if you don't also fix its cause. Also see MOLD PREVENTION GUIDE

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.
