Stachybotrys
Chartarum [: fungi that grow in the form of multi-
cellular filaments, called hyphae] [1]
[Many moulds can begin growing at 4 °C (39 °F), the temperature
within a typical refrigerator, or less. When conditions do not enable growth,
moulds may remain alive in a dormant state depending on the species, within a
large range of temperatures before they die. The many different meld species
vary enormously in their tolerance to temperature and humidity extremes.
Certain moulds can survive harsh conditions such as the snow-covered soils of
Antarctica, refrigeration, highly acidic solvents, and even petroleum products
such as jet fuel. Xerophilic moulds use the humidity in the air as their only
water source; other moulds need more moisture. Mold has a musty odor.] [1]
Mould in vehicle interiors
is unfortunately more common than you would imagine. Although car manufacturers
do their best to keep water and even moisture from getting into your vehicle,
over time, seals wear out and eventually will start to allow water ingress, or
something as simple as forgetting to roll up your windows or closing the sunroof
during a rain storm
Without identifying and
eliminating the source of the mould you can't get rid of it, there are many
Counteractant type products that only mask odours; what you need to do is
remove, clean and thoroughly dry the whole area; carpets, and any padding or
under-carpet materials, upholstery (inc foam and etc) that is affected,
including the headliner and metal floor pan (don’t forget to clean/replace the
cabin air filter).
Just like mould and mildew
contamination in other areas, you cannot wash or shampoo it away. This only
exasperates the problem. Mould is a form of fungus which forms anywhere there’s
moisture trapped in the air, and is spread by releasing millions of tiny spores
into the air. You cannot see the spores but you may be able to see moulds,
grey, green or black in colour, growing on damp surfaces.
Dirt and moisture are essential to mildew
propagation, which is very difficult to eradicate as mould uses enzymes to
digest nutrients from organic materials, the mould forms on top of the material
and also down into its fibres leaving circular or black spots in an irregular
pattern. Mould / mildew needs to be neutralized as it will not dissipate
without treatment as the spores are still present and moisture will regenerate
them
There are hundreds of
thousands of types of mould, but only about ten types cause health problems,
commonly sinusitis, bronchitis and other respiratory conditions, as well as
allergies. I would strongly recommend you wear appropriate personal protection
equipment (PPE) safety glasses, respirators; etc inhalation of mould could be
very detrimental to your health and can cause an allergic reaction
There are many
Counteractants products that only mask odours; what you need to do is remove
and clean and disinfect the whole area; carpets, upholstery (including the
upholstery foam and etc) that is affected, including the headliner and metal
floor pan. Don’t forget to clean/replace the cabin air filter.
Remove the seats and
thoroughly clean the carpet with a carpet cleaner and a disinfectant. Then let
it air dry, or use a heater to ensure that they are completely dry. To
neutralize mould use 10:1 Distiller water / (non-chlorine) bleach solution, use
a syringe to inject solution into seating foam, you may need to remove and
replace the carpet padding.
Test the solution on an
inconspicuous area first to ensure it will not remove the dye. Some carpet
cleaning solutions also contain a fungicide
Bactoshield- is
an all in one safe antimicrobial dry cleaner, stain blocker and deodoriser for
carpets - http://www.4-c.co.uk/carpet-cleaning.html
Sporicidin®
Enzyme Mold Stain Cleaner - concentrate is a blend of enzymes in a low foaming solution
formulated to loosen and remove dried debris, protein, blood and mucin
deposits. It effectively cleans both natural and synthetic fibres that have
been soiled with organic and inorganic debris. Ideal for use as a pre-cleaner
for mould remediation, and restoration applications
Clean the carpet using a
steam extractor’s upholstery attachment, this will eliminate the bacteria that
create mildew, ensure the carpets and upholstery is thoroughly dry before you
re-install the seats
Microban Mildew
& Mold Remover - an environmentally-safe,
anti-microbial formula that destroys mould, mildew, and other bacterial odours
on contact, when you cannot use chlorine The formula is a water-based, non-flammable
bactericide, fungicide, deodorant and anti-microbial, all in one unique
formulation
It eliminates the spores
instantly, and has a long-lasting, residual effect. It may be sprayed by hand
on any surface, or injected into carpet and upholstery padding with our
hypodermic syringe. Environmental Protection Agency (EPA) approved for both
spray and fogging applications (cannot be shipped to CA)
Leather Upholstery – Leather
Master’s Mold Remover (N-Nubuck / Alcantara®)
(A-Aniline / Non-Coated) (P-Protected / Coated) you may notice dark or
white blotches where two areas of the leather touch or areas not used.
If
the contamination is not removed, the fungus will dissolve the leather, forming
small pits. Just like mould and mildew contamination in other areas, you cannot
wash or shampoo it away. This only makes the problem worse. The fungus is
caused by living organisms that must be killed before the leather is cleaned.
This product is effective on most forms of bacterial or fungus growth.
Carpets, Mats and Fabric and Vinyl
covered upholstery Microban Mildew & Mold Remover is an
environmentally-safe, anti-microbial formula that destroys mould, mildew, and
other bacterial odours on contact. When you cannot use chlorine, Microban is a
very effective solution. The formula is a water-based, non-flammable
bactericide, fungicide, deodorant and anti-microbial, all in one formulation (Don't neglect to treat the underlay)
Application - do
not dilute, use full strength, apply via sprayer to porous surfaces until
moist, no not over wet, brush into carpeting, allow to dry 10-20 minutes. Due
to VOC Regulations Microban cannot ship to California
The presence of bacteria and mould in vehicle interiors
Dr. Charles P. Gerba and
Sheri L. Maxwell set out to test the presence of bacteria and mould in vehicle
interiors. There were 100 vehicles involved in the test in the states of Illinois,
Arizona, Florida, California and Washington, D.C., to provide a good
cross-section of climatic conditions across the country.
The following lists
some of the results of their testing’s. “Testing for bacteria and mold” by Dr
Charles P Gerba and Sheri L Maxwell (Professional Carwashing & Detailing –
July 2009)

Personal Protective Equipment (PPE)
Protection
from Potential Health Hazards
1.
Warning:
Always use ground fault protection interruption (GFPI) when using any
electrical device around water
2.
Eye
Protection: I would strongly advise the wearing of safety glasses or visor
when operating any machine polisher.
3.
Ear
Protection; the constant pitch of a polishing machine could affect your
hearing so wearing ear plugs would be wise to protect you from hearing loss.
4.
Hand
Protection; Gloves- with the
verity of chemicals a detailer uses on a daily basis wearing chemical-resistant
gloves resist penetration and permeation, and will provide protection against
dermatitis and chemical burns. Gloves can provide protection, but they must be
chosen with care, the proper selection matched to the hazard is critical.
Chemical-resistant gloves resist penetration and permeation, and cam protect
against dermatitis, chemical burns and corrosion.
5.
Respiratory
Protection (N95): Materials such as aluminium oxide (Aluminium oxide is on
EPA's TRI list if it is a fibrous form) or silicon carbide (Nuisance
particulate-Accumulation in lungs) used in polishes and compounds, and powdered
fillers (Crystalline silica poses a serious inhalation hazard because it can
cause silicosis) and Isocyanate clear coat residue represent a hazard to your
lungs and may cause respiratory distress. Use
a NIOSH-approved half face respirator equipped with a combination filter
cartridge should be worn while using them
6.
Consult the current 3M Respiratory Selection Guide for
additional information or call 1-800-243-4630 for 3M technical assistance.
7.
Material Safety Data Sheets:
Use a ring binder or other filing system to ensure the appropriate MSDS
is always available to identify hazardous substances
8.
Work Hygienic Practices: Rinse cloves under running water before
removing them
9.
Protect
yourself, work safe. As in all things, allow common sense to prevail and proceed with due
caution
Information resources:
1.
Standard and Reference Guide for Professional Mold Remediation,
published by the Institute of Inspection, Cleaning, and Restoration
Certification (IICRC) also contains valuable information
2.
The Environmental Protection Agency (EPA) provides free
brochures to anyone who asks.
3.
The Center for Disease Control (CDC) and a few other
organizations can be considered unbiased and reliable sources.
4.
The National Institute of Safety & Health (NIOSH) is also an
excellent source of unbiased information.
Protect yourself, work safe. Respiratory
Protection; mould spores represent a health hazard to your lungs and may cause
respiratory distress so wear Respiratory Protection. Consult the current 3M
Respiratory Selection Guide for additional information or call 1-800-243-4630
for 3M technical assistance hazard to your lungs and may cause respiratory
distress. As in all things, allow common sense to prevail and proceed with due
caution
Professional
detailers – as
your you’re dealing with health-related issues,
bear in mind that we are living in a litigious society, so document the
process / procedures used on this type of remediation.
