Have you tried Krud Kutter? Its my go to product,
Any vegetable based soap will help remove the oil and grease from the clothing. Also being a heavy weight cotton type you will still see the stain. I own several Jackets manufactured by the same company. They take a great beating and wear very well. But once grease such as this gets into the fibers the staining effect cannot be taken out.
For us carpenters and builders, it is sort of a badge of honor to have these types of stains. Shows everyone how hard we work. The same thing goes with new nail and work pouches. Everyone knows the new guy when he comes to the job in a pretty pouch with shiny tools. Most will put the new pouch on the ground and walk on it and get it all dirty before going to a job.
Take it to a dry cleaner..they use some wonder juice...actually it is a very aggressive solvent. It will not be perfect but much better.
the sooner it's cleaned the easier. If it has ran through the dryer or set to long it makes it harder. First scrape off as much as possible using lifting motions you dont want to grind it in. Then use a thick layer of corn starch and sprinkle it on the stain. Let it set maybe over night. It will absorb a lot if the grease. Shake it off your clothing. Then try Dawn Dish Soap and a tooth brush and scrub. Let it set for a few minutes. Dawn has grease fighting power. If this doesn't work use half ammonia and water. And let it set.
If it has set for awhile or dried use WD40 on it and blot then use the rest of the steps. Depending on how old, what kind of material test spot. If it is a expensive jacket I wouldn't hesitate to take it to the cleaners. I have used this on T Shirts and my Husbands jackets I found this formula over the Internet.
Lestoil- it can be hard to find, but is usually located with cleaning supplies. I think Lowes carries it.
I have also heard Lestoil works but I haven't tried it. Let us know what works for you
Go Jo hand cleaner will get it out. My hubby is mechanic so grease is on clothes ... Just rub generous amount on grease and throw in washer with hot water will bring it right out.
I cleaned door grease off a white lace curtain using Baking soda and Dawn Dish soap. I figured if it can clean Petroleum off wildlife and can get grease out the curtain. It worked, it took a while but it worked. Clean it, rinse, repeat, until stain is gone. I used a kids soft tooth brush to work it into the fabric.
oxyclean and tide in the washer....both hubby n son r
mechanics and carhardts xime out clean
