Soda blasting is and extremely thorough and efficient method to clean up after mold or fire.

We recently did a cat 3 water loss where every stud and joist was affected. Not only did every thing look new when we were finished, but the smell was a true clean, not chemical clean. 1st time clearance is nice also!

you know if you spray straight undiluted bleach on mold is pretty much digests the spores, I know the argument about you can't kill mold, but if you use a powerful enough oxidizer you can digest it, however the health and breathing issues prolly preclude having employees do that, nice job BTW

The great thing about soda blasting is that it totally removes the contamination.

Killing mold and bacteria is simple, eliminating it takes skill.

On a foot note, bleach is not the cure all most people claim it is.

WARNING !!!

Do NOT use Chlorine bleach to kill mold or disinfect moldy areas. It is not an effective or long lasting killer of mold and mold spores. Bleach is good only for changing the color of the mold and watering the roots of the mold.

CHLORINE BLEACH IS INEFFECTIVE IN KILLING MOLD FOR THESE REASONS:

(1) The object to killing mold is to kill its “roots”. Mold remediation involves the need to disinfect wood and wood-based building materials, all of which are porous materials. Thus, chlorine bleach should not be used in mold remediation as confirmed by OSHA’s Mold Remediation/ Clean Up Methods guidelines. The use of bleach as a mold disinfectant is best left to kitchen and bathroom countertops, tubs and shower glass, etc.

(2) Chlorine Bleach does kill bacteria and viruses, but has not been proven effective in killing molds on non-porous surfaces. Bleach itself is 99% water. Water is one of the main contributors of the growth of harmful bacteria and mold. Current situations using bleach re-grew and regenerated mold and bacteria twice the CFU counts than were originally found before bleaching, within a short period of time. Bleach is an old method used for some bacteria and mold. It is the only product people have known for years. The strains now associated within Indoor Air quality issues are resistant to the methods our grandmothers employed to clean-up mold..

(3) What potential mold 'killing' power chlorine bleach might have, is diminished significantly as the bleach sits in warehouses, on grocery store shelves or inside your home or business 50% loss in killing power in just the first 90 days inside a never opened jug or container. Chlorine constantly escapes through the plastic walls of its containers.

(4) The ionic structure of bleach prevents Chlorine from penetrating into porous materials such as drywall and wood---it just stays on the outside surface, whereas mold has enzyme roots growing inside the porous construction materials---however, the water content penetrates and actually FEEDS the mold---this is why a few days later you will notice darker, more concentrated mold growing (faster) on the bleached area.

(5) Chlorine Bleach accelerates the deterioration of materials and wears down the fibers of porous materials.

(6) Chlorine Bleach is NOT registered with the EPA as a disinfectant to kill mold. You can verify this important fact for yourself when you are unable to find an EPA registration number for killing mold on the label of any brand of chlorine bleach.

(7) Chlorine bleach off gases for a period of time. Chlorine off gassing can be harmful to humans and animals. It has been known to cause pulmonary embolisms in low resistant, and susceptible people.

(8) Chlorine bleach will evaporate within a short period of time. If the area is not dry when the bleach evaporates, or moisture is still in the contaminated area (humidity, outside air dampness), you could re- start the contamination process immediately and to a greater degree.

(9) Chlorine is a key component of DIOXIN. One of the earliest findings of dioxin's toxicity in animals was that it caused birth defects in mice at very low levels. This finding led to dioxin being characterized as "one of the most potent teratogenic environmental agents". The first evidence that dioxin causes cancer came from several animal studies completed in the late 1970's. The most important of these, published in 1978 by a team of scientists from Dow Chemical Company, led by Richard Kociba, found liver cancer in rats exposed to very low levels of dioxin. This study helped establish dioxin as one of the most potent animal carcinogens ever tested and, together with the finding of birth defects in mice, led to the general statement that dioxin is the "most toxic synthetic chemical known to man."

I'm going to take that challenge, inaddition, I am going to have it swabbed before the test, immediatley after, and also 3 days after.

I am also going to take moisture readings of the same intervals and strength measurements, both compressive and tensile.

Any restorer that uses bleach is a F#cking Hack! (Just thought I would throw that in.

That depends on species, pourosity, and a few other variables.
What goes into the wood is the root system, while the mold eats at the surface.

The mold eats voids and continues inside as the void deepend from its eating away the surface. These voids are typically microscopic or close too.

So mold can eventually, in the right conditions go all the way through, of course that is typically reffered to as rot.

to find 1/32 to 1/8" is common.

On a crawlspace Job I took 4 samples of soil contaminated with sewage. 1 control 1 added quat. 1 added Bleach 1 added old phenolic microban. All fecal tests were equal to control except Bleach which was zero. Yes millions compared to zero.

So the bleach actually worked on the soil? :eekk: What concentration and how heavy did you apply it? What did you apply it with?

Any precautionary concerns when using chlorine in a tight spaces? Full PPE, air exchange, chlorine gas cartridges?

Just another example of how Chavez has been doing it wrong, first with the toxic encap and now we find out this. What's next???

Richard. We spray with a 12 volt rv pump through a garden hose and a garden hose sprayer. It sprays 20'. Safety guy outside. Forced fresh air into crawlspace. Full ppe. Full face mask. It only takes about 15 minutes. Customers have to be out of home 2 to 4 hours. Put 7 under neg air after spray. Then we rake and respray. Never have had to go back. As for the fecal test I put 1/4 cup in testing container and added 1tbl. of either Bleach quat. or phenol microban. Stirred and sent in. It was 250.00 well spent.

Al, it would beat shoveling out a few inches of soil. We may try that next time we get one. We used to think lime was the answer but then instead of sewage being the hazard we not had lime that could hurt someone that got in there if other work ever need to be done.

The guys are in a crawl space tomorrow but it for mold. Doing a little wire brushing and sanding but not addressing the soil.

Thanks!

Fyi. I only sell and bill it as a deodorizer. 200.00 minimum or .75 SF for just the bleach. We also rake and remove sludge.
