L.G.
Hang an old school clothesline like your grandparents used to use and spray the heck out of them with the hose. I go to a laundry mat so as not to ruin my own washer. I figured out that a combination of Tide with Bleach Alternative, Resolve/Spray and Wash Brite n White Laundry Booster, and Febreeze Laundry Booster/Odor Remover will work MIRACLES! It even almost gets all of the diesel smell. Cleanest oilfield clothes I have EVER seen! Just add all three at the same time like you would add detergent.
