It's super important to NOT have your puppy on any public property (think cement, grass or anywhere) until they have their last Parvo Vaccine at around 16 weeks or 4 months old. Could be a bit longer depending upon if you are consistent with vet visits.
If you have a shared cement space (living in apartments or condos), you can use this video tip to clean the cement.
In a large bucket squirt 3-4 squirts of dish soap and 1/3 cup of bleach and add hot water. It will foam up. Then pour small amounts on the cement and brush with a broom. When finished with area, rinse several times to wash all bleach/soap solution off.
