you get water or olive oil and a cup with hot water in it .put the leather belt in there and wait 15 or 20 min then smell it
Buy clean leather.
Spray VaporRemed on clothes to remove odor first before machine wash.
Tomato sauce (canned works) wiped onto the leather or tomato juice (supposedly) also works.

The new car smell is caused by products used on the leather to clean and preserve it. It is a part of the leather or vinyl. The best way to remove it is to open the windows and allow it to air out. It will fade with time.
Gasoline has a strong, pungent smell that is often described as sharp or chemical-like. This distinct odor is due to the presence of volatile organic compounds in gasoline, such as benzene and toluene. These compounds evaporate easily at room temperature, releasing vapors that create the characteristic smell of gasoline. The human nose is sensitive to these compounds, which is why gasoline has a noticeable and recognizable odor.
About a month ago gasoline spilled in my car when I was bringing home a small tank full for my lawn mower. I thought I would never get the overpowering gasoline smell out, but here is what worked for me. It only took about 24 hours and the car was rid of the odor.

Yes due to its odor
The correct starting point is to use an enzyme based pet urine odor eliminator. There are many brands available at your local pet store or vet. Make sure you test in an non obvious area to ensure that the odor eliminator will not have an adverse effect on your leather. If the odor has seeped into the internals of a seat cushion, then I advise replacement of the seat cushion. If it seeped into the frame, then open the dust cover (cloth under the piece) and apply enzyme based odor eliminator on effected components. It may require multiple doses of the odor eliminator. Finally, if the odor is persistent the place the target piece in an ozone chamber. Your local disaster relief company (flood and fire) should have an ozone chamber.
