How do I kill petrol smell ?

Hello. A few weeks ago, in the back of the luggage compartment, a little bit of petrol ran out of a canister. But I thought, “Fortunately, the stuff is fleeting and soon it will end with the smell…”. Well, of course, he also slowed down over time, but after about six weeks, the fuel is still clearly to be smelled in the car.Therefore the question:How do I get the smell away? Are there housewives tips? Or motor talker tips? All of them have problems with the vehicle, which lead to the smell of gasoline. Unfortunately, I did not find a clue how to deal with such a self-inflicted problem… Thank you in advance. Greetings -v-
