Apple has updated its recommendations and guidelines for cleaning Macs, iPads, iPhones, iPods, displays, or peripheral devices, asking customers not to use products containing bleach or hydrogen peroxide. "Using a 70% isopropyl alcohol wipe, 75% ethyl alcohol wipe, or Clorox Disinfecting Wipes, you may gently wipe the hard, nonporous surfaces of your Apple products," the guideline says.
