You should have put dawn dish soap directly on the stain, prior to washing and when you washed, just used the Dawn instead of Tek Wash...

Tek Wash may have "locked in" the stain now, but your best and really your only option is putting Dawn on it, letting it sit a bit and then re-washing with just Dawn. I would keep doing that procedure over and over until the stain is gone, then another application of Tek Wash, then water-proof it.

It wouldn't hurt to take like a soft wash cloth and rub the stain vigorously with the Dawn to really allow it to break up the oily residue...

Tek wash is not a degreaser, it will not do anything to an olive oil stain... Dawn is basically your only hope...

 

Oils or grease on any fabric? Treat the entire area not just the spot using Dawn Dish Detergent. Allow to soak in for a while, be sure to spread the detergent over a larger area than just the oil stain.

Give it at least ten minutes for the Dawn to do its work and then wash in warm water. It's chemistry actually, ever wonder why so much Dawn is used to clean animals recovered after an oil spill? That's how I learned to use it.

You treat a larger area to eliminate spot effect. This may not work because you have already taken an action prior to asking

The trick is to emulsify the oil molecules that are absorbed into the threads of the material, Dawn is one of the best surfactants that is widely available. I'm not familiar with tech wash but learned about how these things work in school.

Sorry Swinging Fly, we were both typing at the same time

 

Thanks guys! I guess I should have asked first before acting! I'll give Dawn a try, and fingers crossed that I can get more of the oil out of the jacket....

 

+3 for dawn....always works miracles on grease and oil stains in a warm water cycle. I try to soak in the dawn overnight prior to washing. Then, I always hang-dry to ensure the stain is removed before applying Nikwax wash and following up with 10 minutes of dryer cycle on low heat.

 

You might just have to wear it with the oil stain. My old wading jacket was the victim of years of bacon grease, beer, and coffee stains. I think it looked great and it never leaked.

 

Something to be said for that my friend I've never washed a wading jacket or waders however I avoid automotive grease like the plague with any and all my fishing gear. There have been times when I had to make repairs on the boat motor in the middle of nowhere but it's a Honda Outboard and I've always gotten away clean cept for the hands.

 

I usually like to keep my stuff washed between trips but inevitably I become the filth magnet and wind up with food grease or slop in general smeared into my wading clothes. I just got rid of my favorite pair of ski pants an old pair of North Face bibs. they were covered in bacon and egg stains, coffee stains, cigarette burns, whiskey, you name it. My ski buddy used to call the bibs "Delta House". It was like wearing a frat house on a Sunday morning.

 

I couldn't care less about the stain - it's the impact on the jacket's waterproofness that's my concern. In fact, I like my gear to look "lived-in"

 

I have the same jacket.
I believe the middle Goretex layer provides the waterproofing and the outer and inner layers protect the Goretex layer.
The Goretex membrane lets water vapour out but blocks the larger liquid water molecule from coming in.
The grease/oil should have no effect on waterproofing, just appearance.
I agree Dawn is the best oil/grease remover.

I think many also apply a layer of water resistant chemical on the outer later of the jacket which helps shed water as well.

 

How about dawn powerwash spray? I've used it on other clothing items and it worked great. Great on pots and frying pans also.

 

Gotta say that I was very impressed that Dawn did the trick! About 12 days after the spill, following a wash with Nik Wax Tek Wash that I did the day after the spill, I spread "Dawn 4X Platinum" dishwashing liquid all over the affected areas and worked it in by hand then let sit for several hours. Then ran the jacket through a gently double rinse cycle in the (front-loading) washing machine. All olive oil stains disappeared and the jacket looks great with all stains gone! It does have a freshly dish-washed smell to it, but that I can live with. Will test out the water resistance and give it a spray with proofing needed.

Thanks for the tip!
