I actually just got through cleaning after parvo pup. We used bleach on the first day, then we called the vet and asked them about other products like Parvisol..etc. She said that they sell it but bleach is more effective than anything! she said theres probably no way to get parvo out of porous things, like carpet. We diluted the bleach and cleaned the carpet, no discolor so far. Then we bleached everything again on the 5th day.
