does anyone know of any antibacterial carpet powder?
The only thing I've heard of is Borax. I sprinkle Borax on my carpet, let it set overnight, and vacuum it up in the morning. This gets rid of any odors and kills a lot of germs. I'm not sure if it's antibacterial or not but it works great for me and my carpets look like I had them installed yesterday! :) I hope this helps!
