Re: mold remediation update

[Guest guest]

Ms. Rosen,

2 percent hydrogen peroxide will not (I repeat - will not) kill

mold. It will feed it really well and lead to further growth.

fungicide route. Yesterday, the mold remediator sanded down the

wood (the treatment he had originally suggested but had been vetoed

by the hygenist) and washed the wood down with peroxide. The

hygenist came for the 4th round of tests (one pre-treatment and 3

after each peroxide washing). He approved my getting the plumber

in to assess the situation (I want any old pipes that look

problematic replaced now) and the contractor to come in to give an

estimate for the repairs. I am hoping all goes well with this test

so we can move on.

Greg:

Actually the mold count went down considerably after each cleaning with

peroxide. Please give me your scientific source about peroxide feeding mold

growth - I have heard just the opposite. I have major chemical sensitivities

and cannot have someone use commercial products (i.e. s or whatever) in my

house. What NATURAL UNSCENTED mold killer would you reccommend?

Ms. Rosen,

I have never seen a 2% hydrogen peroxide product with an EPA

registration for " fungicidal " efficacy. There is a database on the

EPA's website with a link to CDPR to search for products by active

ingredients.

I have seen bleach or sodium hypochlorite fail with Chaetomium

globousm. Bleach is a much stronger oxidizer than 2% hydrogen

peroxide. I think the workers may have physically removed the mold

rather than kill it. They are supposed to physically remove as much

mold as possible. My issue is the 2% hydrogen peroxide does not

work or you would see many companies selling it as a cheap

disinfectant.

I use a product that has a scent. I use it in a way where there is

no odor after the occupants enter. I know all the chemically

sensitive people will get irate but, you can cut wood with a power

saw and produce formaldehyde. I think the organic chemical scent is

not the issue but how do you manage the environment to mitigate the

scent of the organic chemicals since many organic chemical scents

come from natural sources.

I have noticed chemically sensitive people are often times their own

worst enemy in mold remediation efforts. Mold and bacteria will

produce way more organic chemicals in the form of microbial volatile

organic compounds or MVOCs than any organic fungicide used to aid in

the physical removal of moldy building material. Chemicals (like

disinfectants) will evaporate over time but MVOCs will come back

like a ghost bumping in the night - over and over......into infinity.

Ms. Rosen,

I have a web address for you and others to checkout:

http://www.epa.gov/pesticides/pestlabels/

Fact not fiction.

If you call Liem at the EPA Antimicrobial Division, he will

direct you to this webpage because it is the same database he uses

to see if products are used correctly or if claims are wrong.

I'm just trying to help.
