After using the restroom, I had forgotten that I ran out of aerosol, scented air freshener. So I used what was nearby: cucumber watermelon body splash.
A couple of squirts above the toilet. It cleared the air, and it smelled really nice without hurting the environment.

Instead of buying air fresheners to spray in your bathroom or anywhere else in your house, I use my old body sprays.
