Want your shiny new console to stay that way?
Splash some alcohol on a cloth, and gently wipe down the entire console.
With the second, dry cloth, wipe down your console again.
While paper towels will work just fine for this, they can leave behind bits of fuzz or dust.
If you want a truly shiny PS5, try using a lint-free cloth.
Sometimes cleaning your controller with alcohol can help unstick sticky buttons if you ever run into that issue.
