These heavy duty nitrile gloves keep my hands clean when an automotive emergency pops up. Frequently my 43-year-old motorcycle and 32-year-old VW bus hiccup. Usually, they do it when I am wearing something I do not want covered in grease, and am far away from home. Luckily both vehicles have nearly full sets of tools in them, and I can usually get to work wherever need finds me. Keeping my hands clean, however, not likely until I started keeping a handful of nitrile gloves in each. I tried keeping a pair of shop gloves in the car, but they got lost quick.
