The topic was how to kill the carpet odor from a toilet overflow. I have not had to deal with that problem, but have had dog urine in the carpet that will stink. I eventually discovered the enzyme products that break down the urine proteins and eliminate the odor. It takes a few days for them to do it. The brand name that I use is "Simple Solution" because it is the least expensive and yet still works great. Such products are generally available where pet food is sold.
I would give the enzyme products a try before using bleach. - Gil Laster, Charlotte, NC [Non-text portions of this message have been removed]
