What is the correct procedure for disinfecting surfaces contaminated with blood?

Cleaning with soap and water then disinfecting
Disinfecting directly with alcohol
Using a disinfectant wipe
Using hospital-grade disinfectants

The correct answer is: Cleaning with soap and water then disinfecting

Cleaning with soap and water first is necessary because it removes any visible blood and can also help decrease the number of germs on the surface. Disinfecting directly with alcohol may not be effective if the surface is visibly dirty or there is a large amount of blood present. Using a disinfectant wipe is also not recommended as it may not adequately cover the entire surface. Using hospital-grade disinfectants is not necessary for most surfaces and may be harsher and more expensive than necessary.
