Do-it-yourself, easy mold clean up suggestions


There are different condition levels of contaminated environments/materials which require different cleanup methods.


The information provided on this page reflects the recommended methods of clean-up for “Condition 1” or “Level 1” or less, contaminations.  These are situations which involve smaller areas and degrees of mold contamination or areas of former live mold contamination. 


In all cases the, use of appropriate personal protective equipment is necessary to protect those performing mold clean-up efforts from illness.


Personal Protective Equipment (PPE) for Condition/Level 1 clean-up:


-N95 disposable respirator (mask)




-Disposable gloves


Materials Cleaning:


Visible surface mold should be “misted” (not soaked) before cleaning using a standard spray bottle with a Borax solution. 


Larger mold contaminations, visible or hidden, should be killed prior to cleaning and restoring.  Killing the mold with high concentrations of ozone will achieve this.  There should be no persons, pets or plants present in any space where ozone treatments are in progress.


Non-porous items/surfaces, such as metals, glass and hard plastics, and semi-porous surfaces such as wood and concrete, that are structurally sound and visibly moldy can be cleaned and reused.  Cleaning should be done using a solution consisting of 1 cup of Borax to 1 gallon of water and soft cloth or soft-bristle scrub brush.  If stains remain, Oxalic Acid can be used to attempt to remove the stain.  Be sure to use caution as Oxalic Acid is poisonous.  Read all instructions on the container of the Oxalic Acid and wear appropriate PPE.


Porous items/surfaces, such as wallboard, drywall, and fabrics that can be cleaned, can be reused – but should be discarded if possible.  Again, a Borax solution should be used.


Ceiling tiles, insulation and similar materials should be discarded by bagging and placing in the trash.


All materials and surfaces to be reused should be completely dried.  Any surface to be painted should be primed with Bin primer/sealer or similar alcohol-based primer/sealer prior to painting. 


Bleach can be used on clothing and other household fabrics in order to remove stains.  Be careful to use the appropriate bleach or colorfast bleach as you would normally launder clothing.


The use of biocides is discouraged as they can pose health concerns for people in occupied spaces.


There are many different processes for cleaning many different materials such as wallpaper, leather goods, bedding and pillows, photographs, prints and carpets. 


Killing the mold before cleanup is key for almost any cleanup project.  Call Action Ozone for helpful tips and instructions on killing mold, preventing moisture intrusions, and cleaning assistance.
