Electrostatic foggers for bulk decontamination
« on: April 25, 2020, 04:12:09 PM »
I've been doing deep, deep research for the nursing home on large-scale surface decontamination -probably using hydrogen peroxide-based disinfectants. (I'm looking for effective, generic, cheap, and readily available).  I was tipped off to this tech from a few articles & slideshows in my feeds showing cities disinfecting mass transit. What I mostly found was a couple of companies hawking their proprietary, *patented* h202 solutions.  This smelled of the old Gillette razor blade marketing and Debbie said it wasn't going to be cheap.

To cut to the end of a long chase, here's what I've found. EXTRA points because I also found EPA documentation and registration numbers (not all listed in this thread).

Electrostatic Spraying - Multi-Clean
https://multi-clean.com/wp-content/uploads/2018/02/ElectrostaticSprayingWhitePaper3-1-18.pdf

The product they appear to be using is

Multi-Clean 256 Century Q Disinfectant Cleaner (EPA registration No.
47371-129-5449) has demonstrated effectiveness against viruses similar
to the 2019 Novel Coronavirus (COVID-19) on hard, non-porous surfaces.
Therefore, Multi-Clean 256 Century Q Disinfectant Cleaner can be used
against the 2019 Novel Coronavirus (COVID-19) when used in accordance
with direction for use against Adenovirus type 7 on Hard, Non-porous
surfaces.
https://cougarchemical.com/products/multi-clean-256-century-q-disinfectant

THIS SITE sells a concentrate
One case of #256 Century Q will make 544 gallons of disinfecting
cleaning solution.
($132 for 4 x 2L bottles = 544 gallons)

The gun shown is here, but there are several other brands of electrostatic foggers out there (but currently all sold out)

found more...

Electrostatic spray technology has been around and used in paint spraying for over a decade.  The hard part is to find an effective, generic, cheap, and readily available disinfectant, which now looks do-able. THEN I'll worry about how to apply it.

I just made a disinfectant order from APR Bio-Tech (thank you Littleman) and noticed that one of theirs specifically says that it works in electro-static foggers.

That got me looking at the machines. Very hard to find and often pretty pricey.

And yes, the Victory guns on Amazon look like toys. They remind me of the cheapo Wagner paint guns, which mostly are garbage compared to a pro-level Graco.

Also, have you learned how long these electrostatic fogs linger? I don't want to be breathing CV19, but I also don't particularly want to be breathing hospital-grade disinfectant aerosol either. I think I would take my chances with CV19 before I did that frequently.

I really like the idea of the UV disinfecting robots, but $80,000 is a bit pricey for the home user (price as per this article):

Thanks, I'll dig it up.

No.  And this is what I don't like about water-based disinfectants. This is the BIG advantage of ozone generators, IMO.  If you're doing this for your rentals, I'd definitely go O3 for coverage and penetration. And it is cheap.  And it deodorizes, to boot. They're supposedly legal in Calif for hotels.

I'm thinking that the nursing home should forego the 'electrostatic' and go with a Ryobi portable fogger.  These received solid reviews and sold for $100 at Home Depot.  Now sold out everywhere, the scalpers have them selling for $400-up, but they'll come back down eventually.  The negative is that they're going to use more disinfectant.

This page, slide 4, mentions electro static

The bulk surface disinfectant is out of stock, but we got some of the bulk hand sanitizer and wipes, safe for basically all surfaces. So the aloe vera will keep the granite countertops smooth and supple

I picked up a supposedly new Ryobi fogger on fleabay for $300 delivered.  Maybe I won't get a box of bricks.

But Amazon will not ship it to me in California. Illegal since 2007, apparently.

So ship it to an out-of-state friend as a gift and pick it up whenever.

>illegal

But waived for hotels, so I'm told.  You should check that.  Hotels = accommodations = cabins would be my logic.

The nanny state has good reason to keep it out of consumers' hands.  I've told Louise that I wouldn't recommend it to --ummm-- inattentive friends & relatives.  They'll fry their lungs.  But for those that are capable, it is too good and too easy at what it does to pass up.

You are making questionable assumptions about me, not always borne out by evidence.

https://foreverozone.com/we-sell-ozone-generators-to-california/

Short version: ozone generators are approved in CA for "shock" treatment at high concentrations, but not for use as air purifiers in occupied rooms at low concentrations. I guess the problem was that a lot of people were selling ozone generators as a healthy way to keep your room air clean.

Since Amazon doesn't want complications, they just ban shipping them to California, but other places do not, since it is fully legal when used as designed.

This one is good for up to 1000 square feet at 50% humidity.

But on the other hand
Why aren’t ozone generators, UV lights or air purifiers on List N? Can I use them to kill the COVID-19?
"EPA only recommends use of the surface disinfectants identified on List N against SARS-CoV-2."
https://www.epa.gov/coronavirus/why-arent-ozone-generators-uv-lights-or-air-purifiers-list-n-can-i-use-them-kill-covid

So, if your goal is to meet the AirBNB requirement of using a listed disinfectant, neither the disinfectants based on benzalkonium chloride (as posted elsewhere) or ozone will meet that requirement.

>Ryobi fogger on fleabay

Arrived ok, new in box.

I gave it a test run, it's more of a "fine spitter" than a fogger. It has potential, but only in places that can withstand a wet film of liquid, such as a warehouse, receiving dock, or inside a delivery truck body.

It'll definitely work for outdoor pest & weed control.

Where did you get to with these foggers?  I have been recommended to use one for the holiday let, and of course no one know about o3, so they are playing dumb.

The issue is the turn round time.... 2 hour O3 running the 2 hours with the windows open. They only have 5 hours for the complete turn round. (that can be changed of course)
