About:
Keyboard Cleaner is a lightweight utility that creates an overlay shield across the desktop, effectively blocking all keyboard input to prevent accidental keystrokes. It acts as a keystroke interceptor, ensuring that no unintended commands are executed while you clean your keyboard or temporarily secure your workstation. This tool is ideal for users who need a simple, immediate way to lock input without suspending system activity.

Key Features:

Full-screen input blockade
Minimal system resource usage
Simple toggle activation
Visual overlay indicator

Use Cases:

Physically cleaning a keyboard without triggering system commands
Preventing accidental input during presentations or screen sharing
Temporarily locking a workstation for short-term security

Alternatives:

Karabiner-Elements – Offers complex key remapping and temporary key disabling, but is heavier and more complex to configure.
System-level screen lock – Secures the session but requires full re-authentication, making it less convenient for brief interruptions.
