Awesome results thanks for sharing!
Now can you use the oil dri after you clean a driveway?
Yeah. But oddly, I have oil stains that seem almost “set in” after cleaning. It’s best to do it before.
I can attest to this. I recently put oil dry down on an oil stain, crushed it in with my foot and just let it sit for about a week. Came back and its completely gone. Never thought it would work, but figured I’d give it a try. Didn’t even rinse, just swept up the oil dry.

Okay, so now I’m convinced to use the oil-dri. @squidskc I am cleaning the driveway that asked me about oil stain removal, for yearly HOA maintenance. I know above someone asked about using it after driveway cleaning. Would it be more beneficial to crush it in after the cleaning while it’s still damp, or go back after several other drives and put it down while it’s dry?
It would be most beneficial to stop by, drop the oil dri, crush it into dust with your boot, then not come back for a week…THEN wash it.

Unfortunately that is not an option, considering I’m only part time as I teach full-time and they live an hour away. I scheduled multiple jobs in the neighborhood on one day to maximize my time.
I would still suggest a week between when you use the kitty litter and wash. If you can’t then you can’t…but that is the best way.
I understand. They aren’t desperate or anything to have it removed, they were just asking if it was possible. But otherwise, they just want the yearly clean.
I just when through this in my own driveway, changing pump oil and had quite a bit of oil leaked on concrete when a drain line slipped. It started raining,.I ground ikitty litterin as best I could and just left it. Rain passed a couple days later there was almost no little left and no oil stain. Time is key.

@CaCO3Girl and @MDA1775 are right. Let it sit for a month. Or a week. Or six months. But time is key. Make some company letterhead and draft a letter to the HOA saying that it needs time.

Can you use oil-dri after you have pressure wash the driveway? I do not want to ‘set’ the stain if surface cleaning has that affect on it. You know what I mean ? So I guess I’m asking if I should do this before or after service
Answered my own question by reading alittle more carefullly!. I have a customer who wants these oil spots removed, poured down oil-dri and danced all over it like a fool but it’s grinded into the concrete pretty well. We shall see what happens in 1 week when i come back to pressure wash! I’m also going to post treat any shadows that I see with chomp pull it out remover. Test that’s stuff out. Also, I’ll be washing with cold water. So to all my cold water guys trying to get rid of oil stains, stay tuned. I’ll explain my process in detail in a week.

Good luck, looking forward to the after pics.
I read some of the reviews and they were saying it is like a white paint on the surface. I don’t know, I have never used it.
I read that too. A few even said the “white paint” wouldn’t come off and made the concrete worse than the oil stain. I’d definitely test it on your Chief Master Sergeant’s parking space on base before a customer’s driveway. @DJPWS 
It looks like the only ingredient listed on the sds is d-limonene. D-Limonene is what’s extracted from orange and other citrus fruit peels. It’s the ingredient used in the citrus cleaners you see. It has many other uses. With the Pull it Out they must infuse it into poultice or something. Will be interesting to see how it turns out. I wonder if it will only take care of a more recent oil stain? It would be awesome if it would work an older oil stain that’s been there for years. Keep us posted.

MY LITTLE BIT OF EXPERIENCE has me believing that old oil stains can only be fixed when the concrete is replaced or painted. I tried CHOMP several times before giving it away. I’d like to know of anything better, but a strong solution of lye with some surfactant works better for me than anything, and it’s really cheap.

I’ll do a test spot when I get it and let you know, I won’t put this stuff on their driveway until I know the result from testing. Any lye product recommendations for someone who uses cold water ? Or do you suggest 100% lye powder mixed into some water
I have a super expensive hot box that runs about half the time (Thanks Landa) and can tell you that the best thing about hot water is that I didn’t freeze my nuts off during the Winter while using it. As for the solution, I would simply use the industrial NaOH at 25%, mixed onsite because it’ll create it’s own heat and be more affective, adding your favorite soap or surfactant to make it wetter and more powerful. Let it sit for 10 minutes, use a surface cleaner to scrub out the grease you just melted. HAVE FUN!!!
