Apple has added a section on their website about how to clean your Apple products, and while Samsung has not released a statement saying this, with very similar screens and materials, following the same practices should get your devices nice and clean. Some things to avoid using to clean your device screens are window cleaner, kitchen cleaners, rubbing alcohol, and any other liquid as these can do harm to your devices. For all other surfaces just use good old disinfectant wipes such as 70% isopropyl alcohol wipe or Clorox Disinfecting Wipes and you’re good to go.
Of course, try to clean your hands before cleaning anything else so you don’t re-contaminate with germs from your hands. Clean your hands with an alcohol-based hand rub or wash them with soap and water for at least 20 seconds, and avoid touching your eyes, mouth, or nose especially with dirty hands.
