So, reading through the above Food Safety article, it looks like ozone-infused water makes for an effective, no-rinse decontaminate spray for surfaces (with a pot life of 30 minutes). 

Ozone-enriched water kills microbes as effectively as chlorine, and since it is generated on-site its use eliminates the need for personnel to handle, mix and dispose of harsh chemicals for sanitation. Further, since ozone readily reverts to oxygen, an end-product that leaves no residue on contact surfaces. Ozone-enriched water can be sprayed directly on floors, drains, walls, wettable equipment, tanks (externally and internally), and clean rooms via mobile or centralized systems with hand-held or drop-down, low-pressure sprayers.

I've ordered one of these;

An article somewhere said O3 air runs rodents and insects out of the room (to adjoining rooms).  I suspect that's one of the reasons they're using it at grain bins.

>mildew

I had a few spots of mildew in the garage I'm using as a decontamination chamber.  They're now gone.

If you'll look at that Ozone Tunnel, it looks as if there is some sort of misting going on.

Sanitize groceries, discard takeout containers immediately: Doctor demonstrates 'sterile technique'

The little (500 ml/hr) ozone generator arrived and is pretty handy.  I found big, deep pan in the attic and set it up in the garage.  Produce is dumped in there directly from the car and 'bubbled' for 1/2 hour.  We're likely to keep using that over the long term because it is easier to prep vegetables than washing with soap and likely to do a better job -particularly on leafy or deeply creviced items like cauliflower.

Louise likes the small size and output, so after the vegetable-cleaning duty she placed it in bathrooms around the house and let it run for an hour.  Last night, she set it up in the kitchen before going to bed.  That should work for 'spot sanitizing' fairly well.

Yes, the 12v model should work well in your off-grid environs, Damian.  Getting enough concentration is the trick and a sealed vehicle makes for a good decontamination chamber.

After we unloaded the groceries yesterday, I ran an extension cord out the garage door and ran the big O3 unit in the van for a few minutes.

I put an office fan behind mine.... I just feel it helps circulate the o3 round the room better.

You don't want you and ozone in the same room.

  Oh no. dont do that.
