Gas tank handle have so many germs on them, because so many people touch the handle on a daily basis. my idea is to have a retractable santizer in the door of the gas tank for every car you make. and the santizer can be replaced every couple of weeks. which can be purchase at walmart for a small price. and can be replace by the owner of the car. ford maker the retractable santizer on the inside of the gas door. and walmart sells the santizer glove. or any autoparts store.
