Is it ok to use a disinfectant on my Apple Watch?

Using a 70 percent isopropyl alcohol wipe or Clorox Disinfecting Wipes, you may gently wipe the exterior surfaces of your Apple Watch, Sport Band, or metal band. Don't use on fabric or leather bands. Don't use bleach. Avoid getting moisture in any openings, and don’t submerge your Apple Watch in any cleaning agents.
