I was told that even bleach wouldn't kill the virus, also. Going to research now. Thanks, Michele!
OP, I'm so glad to hear that Mag is responding. Praying she whips Parvo's butt!!
Okay, per ASPCA (
http://www.aspcapro.org/canine-parvovirus.php ) :
Fortunately for shelters, regular household bleach (sodium hypochlorite) is one of the most inexpensive means of neutralizing parvovirus. It should be diluted 1 part bleach to 32 parts water (or 4 ounces of bleach to a gallon of water) to make it safe to use around animals yet still be effective.
Unfortunately, many quaternary ammonium products commonly used in shelters such as Parvosol, Kennel Sol or A33 are labeled as parvocidal, but multiple studies over the past several years have proven they are not very effective.
Another parvocidal disinfectant is potassium peroxymonosulfate or Trifectant®. It is readily available to shelters and has been proven to be parvocidal. Three advantages of Trifectant over bleach are that 1) it has better activity in the presence of organic material and 2) it does not have to be prepared fresh daily like bleach and 3) it is less corrosive to metal surfaces or mucus membranes than bleach.
Whichever disinfectant is used, the surface must be clean before the disinfectant is applied, and it should remain in contact for 10 minutes before rinsing.
