no buddy is really saying much so I will tell you how I use it, I have pretty much totally switched over to a powdered sodium p, it has unlimited shelf life and always mixes strong and fully effective,
1) mix sodium p with ammonia= stain magic, to be used on organic stains, dog shit, blood, ketchup, worked great on an old orange juice spill, etc, sometimes it can help contain or take out an ink stain that explodes with solvent application
2) mix sodium p with prespray, this works great on yellowish animal piss stains,
3) mix sodium p with a high PH product and you have a serious tile and grout cleaner.
4) some people like to mix it with their prespray on olefin carpets, however I haven't seem much difference doing it so I just stick to my olefin specialty prespray in this application.
the disadvantage of using sodium p over liquid peroxide is that it uses soda ash as the carrier, which doesn't dissolve all that well, and can clog some sprayers, its best if you mix it and let it sit for a while before using. sodium p is cheaper and easier to deal with than making frequent trips to sally beauty supply
there you go there is my take on peroxide and what it does as it applies to general carpet cleaning, I am sure others will add more
