Hydrogen Peroxide is a minor miracle. I've gotten many cuts and gashers over the years. Several times they have gotten infected. Sometimes badly infected with red lines growing towards my heart.
BUT, every time I've been able to take an abrasive pad, scrub the **** out of the wound, open the wound up, pour hydrogen peroxide into the wound, and it magically cleans it out. After doing this several times a day the infection disappears.
I say this because the deep cut on my hand from a few days ago keeps getting reinfected because I continue to use it. I can't really cover it up either. Then every evening, night, and morning I treat it with hydrogen peroxide and bam the infection goes away. It's slowly healing too.
So, if you get any wounds remember that hydrogen peroxide is your friend.
