Hydrogen Peroxide is swell stuff.

But at 35% concentration it’s kinda powerful and hazardous stuff. Not to mention, pricey.

If it spills onto anything other than very clean glass or plastic, it’s going to release a lot of heat and steam and oxygen.

So it’s probably banned from the mails and UPS and anything other than high-priced truckers.

The Germans used it in the V2 rockets in ww2. They also used it as oxidizer in a rocket-powered plane.
Only problem, in a crash, the Hydrogen Peroxide could leak into the cockpit and bleach and then dissolve the pilot.

I doubt if you want to buy the stuff to "disinfect" or de-smell your septic tank. At over $10 a gallon, it’s a very expensive and hazardous version of Febreeze.
