Several products commonly found at home can remove the smell of gas, depending on where the odor is located. These products include vinegar, baking soda, vanilla extract and lemon juice.
To remove gas odor from the skin, use vanilla extract with some water to rub the areas where the gas came into contact with the skin. You may also use lemon juice and vinegar mixed with water. Finish by taking a shower to remove any remaining odors.
To remove the smell of gas from a home or car, combine hot water and vinegar in one bowl and hot water and baking soda to make a paste in another bowl. Clean up any remaining spilled gas and wipe the area thoroughly with the vinegar solution. Then apply the baking soda paste to the area, allow it to set for a few minutes and remove it with a rag or your vacuum. Finish by thoroughly cleaning with plain hot water and allow to air dry.
