You have at last found the fuel leak that had been a problem for several days but now you can’t get rid of the smell of gasoline that pollutes the interior of your GMC Sierra.
If you have not quite identified the origin of the fuel smell, we advise that you have a look at our article on the subject: “GMC Sierra smelling like gasoline”.

However, if you have identified it, we will explain how to solve it and restore a healthy smell in your GMC Sierra.


Different steps to remove the smell in your GMC Sierra

First of all, if the fuel source is inside, you must find it and absorb as much as possible. Make use of old cloths or mops that should be discarded after handling as they will not be reusable.
For the remaining fuel that you cannot absorb inside your GMC Sierra, use the support of the sun. Indeed, if you keep your vehicle in full sun for a few hours, some of it will disappear.
Now, for the remaining part, you need to prepare a cleaning mixture.
We advise using carpet shampoo mixed with water. Prepare this in a bucket to come with a homogeneous mixture. It will be efficient for your GMC Sierra. Apply vigorously with a cloth or the green side of a sponge. You will also have to throw away what you use here.
Another usable mixture is a mixture between a third of water, vinegar and finally baking soda. Also very powerful in eliminating odours in your GMC Sierra.
Rub vigorously for a few minutes. Then, you must dry out as much of the area as possible by absorbing with different cloths. The sun will do the end of the work.

Now that the stain is cleaned, here are some suggestions to permanently remove the smell in your GMC Sierra.
First reflex, an anti-odour spray, special for cars. Be cautious, however, if you have leather or other coating in your car. Take something appropriate.
Alternatively, you can employ baking soda, which will absorb these unpleasant odours of your GMC Sierra. Sprinkle the area and let it work for a few hours. Repeat the operation for several days for an ideal effect.
Another very powerful product that we don’t necessarily think about is cat litter. Indeed, this is basically intended to keep and absorb the odours of cats that are long lasting. So it also will work very well for your GMC Sierra. It is recommended to let it work a little longer than baking soda (a full day would be very effective).
Finally, we encourage that you use ground coffee in the spot in question, it also has very powerful odour absorbing effects.

Here are the different tips you can practice to find a clean and odourless interior.
