Gasoline fumes are heavier than air. They concentrate in low areas. There is no safe way to use gasoline. Squirting a gasoline fire with a water hose only spreads the gasoline and fire. Anyone who uses gasoline for cleaning is asking for trouble. And especially anyone who uses a spray bottle to atomize the gasoline.
Now, you have been informed so you can't claim ignorance. Remember the quote from Forrest's mama.
