Did a no brain thing last weekend. moving some of my equipment around in the (attatched) garage I knocked over a gas can and spilled about one gallon of gas. I quickly got a garden hose and washed the gas out the garage door (the spill was right at the door maybe 3 feet in) Anyway now one room of my house just stinks to high heaven of gas. I have no clue how a gas spill right by the garage door that was washed out within three minutes of being spilled can stink up a house but this is nasty. Any suggestions?
