If you are working with diesel fuel, you need to be careful you don't spill any. Spills can be cleaned up, but the odour is very strong. It can remain for a long time, regular air fresheners are not effective at removing a diesel smell. If you get the diesel on your clothing, you will need more than your regular washing powder to remove the diesel odour.
Lay mothballs around the room that had the diesel spill. Obviously you don't want to do this inside of your home if you have pets or children, but it is a great option for your garage or the back of your car. The mothballs are successful at neutralising the odour.
Wash your clothes in Listerine if they have diesel on them. This is what firemen use to get the smoke smell out of their clothing. If the diesel was spilt on a floor or car mat, you may want try rubbing some Listerine in it. Then use a carpet shampooer to wash it clean.
Spray OdorGone in the air of the room that smells like diesel. This product is all natural but very strong. It was created to get rid of some of the strongest odours. If the odour is on your clothes, you can spray them and let them sit awhile before washing. You also have the option of spraying the OdorGone directly on the diesel stain.
Combine hot water, ammonia, washing soda and vinegar in a clean empty gallon milk jug. Shake the jug and then use it to clean the surface where the diesel was spilt. This will clean the area as well as eliminate any odours.
If you get the diesel on your hands, wash them with hand sanitiser. The hand sanitiser will get rind of the smell.
Keep a lid on any containers that you are using to transport your diesel. You may also want to lay an old towel down in your trunk in case the container leaks. Then you can just throw the old towel away.
