In Roblox Examination , the blood on your mask is usually wiped with the Y key on keyboard, or Y / Y on controller according to a beginner’s guide for the game. A TikTok result also shows players asking about “wipe blood,” which lines up with that control hint.

How to do it

  • Press Y to wipe the blood off your mask after a fight.
  • On controller, use the same listed input shown as Y / Y in the guide.
  • If it still does not work, you may need to be close enough for the game to register the action, since the guide frames it as a post-fight mask-cleaning control rather than a menu option.

Quick note

This is about the game’s mask-cleaning mechanic, not a real-world cleanup method.
