HYDROGEN PEROXIDE GETS STAINS OUT OF MY CARPET SINGLE-HANDEDLY IN 2 QUICK STEPS

Hydrogen Peroxide gets out pet stain and odors from my carpet, along with those mystery dots from who knows where. 

Kroger sells a nice flip top jar for a great price.

1.  If obvious moisture is on carpet, absorb it first.  (Note to newbies:  Do not force moisture deeper into the carpet by rubbing.  Instead, lay an absorbent cloth or paper over the wet area, and then step on cloth or paper until moisture is absorbed.)
2.  I just open the top and squirt liberally. 

No wiping, no anything. 

When it’s dry (might take a day or two, depending on size of stain), if stain remains, or comes back, simply repeat. 

Eventually (usually no more than 2 or 3 applications) stain is g o n e! 

The odor disappears too!

Exactly why this works, only the Lord knows, but I found a possible explanation at Educate-Yourself.Org, (Williams 2003)from some doctor guy.  It seems hydrogen peroxide is a very common substance.  In fact it’s almost water.  I said almost—DO NOT GO DRINKING IT!!! 

The stuff we buy has yucky additives anyway, but pure hydrogen dioxide ingestion can be FATAL.

Now that we’ve got that out of the way, what it is, is:

Water with an extra atom of hydrogen. 

Chemically: 

H2O2   (Water is H2O, remember?)

If I correctly understand the gist of what Dr. David G. Williams says in his article, the extra hydrogen comes from “O3” (ozone). 

If any substance is interesting, it's hydrogen peroxide. Hydrogen peroxide should really be called hydrogen dioxide. Its chemical formula is H2O2. It contains one more atom of oxygen that does water (H20). By now everyone's aware of the ozone layer that surrounds the earth. Ozone consists of three atoms of oxygen (03). This protective layer of ozone is created when ultraviolet light from the sun splits an atmospheric oxygen molecule (02) into two single, unstable oxygen atoms. These single molecules combine with others to form ozone (03). Ozone isn't very stable. In fact, it will quickly give up that extra atom of oxygen to falling rainwater to form hydrogen peroxide (H202)
