the best thing i have found for diesel, gasoline, kerosene, deet/insect repellant or anything else with petroleum in it, is to wash up real hard with some COLD water and a pumice bar. Then wash with warm water and Dr. Bronner's natural soap. Every time i use hot water to wash it seems to jsut intensify the smell. Dr. Bronner's is all natural vegetable glycerin soap and isnt strong enough to get the grime off so thats why i use a pumice bar. Works wonders.
