The American Society for the Prevention of Cruelty to Animals (ASPCA) recommends washing all infected surfaces and items, such as the dog's nowl and toys, when disinfecting a home after parvovirus. This is done effectively with a solution made with 1 part chlorine bleach to 32 parts water. Surfaces that can't be washed with chlorine bleach may be steam cleaned or quarantined to protect other animals in the home.
All dog bedding, collars and other disposable items that cannot be cleaned with chlorine bleach should be thrown away to prevent the spread of parvo. Couches, other soft furnishings and carpets may be steam cleaned, but parvo may remain on soft surfaces for up to six weeks even after cleaning.
Hard surfaces and non-porous surfaces such as linoleum flooring are disinfected by mopping with the solution of chlorine bleach. Clorox recommends cleaning hardwood floors with a solution of 3/4 cup chlorine bleach in 1 gallon of water. The solution needs to remain on the floor for 10 minutes to kill any remaining virus. Dog bowls and other items that the dog has used should also be soaked in a solution of chlorine bleach for 10 minutes.
Concrete areas can be disinfected using a bleach solution, spraying concrete patios and driveways thoroughly with a pressure washer after treating with bleach. Gravel driveways and treated wooden decks in non-grassy outdoor areas can also be cleaned with a bleach solution by attaching a sprayer bottle to a garden hose and using 3/4 cup of chlorine bleach to each gallon of water in the sprayer. Grass may be flushed with plain water to reduce the amount of parvo virus in soil.
