I've since found out it will remove almost any stain. The vineagar is good to use just to get better smelling clothes. My hisband is a diesel mechanic and I have had to wash his uniform for over ten years. I find that washing them in hot water with Tide with Bleach and drying them with a fabric softener sheet works fine. I just put it in my fabric softener dispenser.
Oil Try adding a drop or two of eucalyptus oil to the wash after filled with water.
My fianc e drives a semi-truck and always seems to be getting either diesel fuel or axle grease on his clothing. The best thing I've found to remove the stains and smell is to pre-treat the clothing with Dawn dishwashing detergent, and then wash them as usual. I have even added some to the whole load to get rid of the fuel smell. There's even a free weekly email newsletter. All rights reserved unless specifically noted.
