Excellent Overnight Concrete Stain Remover – Worked Better Than Expected
I used this product to remove a stubborn oil stain on my concrete driveway that had been there for months. I applied it in the evening as directed, making sure the surface was clean and dry beforehand. The application was very easy—just pour and spread evenly over the stained area. By the next morning, I could already see a major difference. The stain had significantly lifted, and after lightly rinsing the area, the concrete looked almost like new. I was especially impressed with how well it penetrated deep into the porous concrete instead of just cleaning the surface. What I liked most: • Fast-acting overnight results • Easy application process • No harsh chemical smell • Works on old and set-in stains • Restores concrete appearance without pressure washing This is a great solution for removing oil stains, grease, and other discoloration from concrete driveways, garage floors, or sidewalks. I would definitely recommend it to anyone looking for an effective and low-effort concrete cleaner.

Outstanding Product
This stuff is fantastic, and I would recommend it to everyone I know. It works as it should, pulling the oil drops right out of my pavers. Going to order another bottle just to have an extra on hand.

Works Pretty Well!
So, I gave it 4 stars purely because, while it does clean the spot well, it does leave a bit of residue. As you can see in my pictures, I have a fairly deep ATF stain on my driveway from my truck deciding the front seal on the transmission didn't want to be a seal anymore. It was about half a quart dumped onto my driveway and has been sitting for 3 weeks. The first few pics show a similar amount of the material, but one dollop spread out. As you can see, the effect from either is basically identical, so you can spread it and save yourself from using way too much! As for the next series of pictures, I did a second coat to see if it would pull more of the stain, and it seemingly did! But with obviously diminished returns. The difference is stark at least! And it seems to have removing a large portion of the ATF stain at the least. The first application was for ~30 hours, the second was for 12 overnight. Each instance when clearing it, I used a special brush with a hose attachment to dissolve the powder into solution first, and then brush it off as liquid so my lungs wouldn't get blasted by the powder. The powder is fairly egregious once brushed dry and will mess with your lungs.

Great Results
This product worked great. It did take longer to dry into powdered form (two days) than they claimed (12 hours) but it removed the oil stain completely. Highly recommended!

I wouldn’t use on asphalt.
Arrived quickly which was nice. The bottle was larger than we had expected. We applied per the instructions. It did work but not very well. It did lift the oil but it also seemed to disintegrate and lift the asphalt. I would think it would best for concrete only. Their was no smell or odor. We did try to wash away any excess after following directions but we still have giant white patches.

IT REALLY WORKS !!!! Real review .. don’t waste your money with others!
THIS WORKS!!!!! Real review and I tell you this works! I struggled trying to find a product that really worked. This was the 5th product I tried after no luck with the others. The hoa was coming down hard on me after my car leaked oil in the driveway. I hired a professional guy to power wash my driveway and he did and the stains remained! I took matters into my own hands vowing not to waste anymore money hiring another power washer. This did the job !! I tried the oil eater regular version and while that worked a bit it’s not the best for really deep oil stains. I put it down left it over night and the next morning the liquid had turned to dust. I had to wash it off because the white residue still remained and man was I surprised that all the oil stains were gone !! I thought they were here to stay forever! I’m so thankful to have found a product that finally worked !!

Highly recommend!
This worked GREAT! My husband thought it was a good idea to drag our grill out into the driveway and feed the neighborhood burgers and hot dogs. When the party was over I was so upset to see that there were two huge grease stains on the driveway. I thought they would be there forever. But I ordered this product without much faith. But it totally worked!!! And it was super easy to use! Highly recommend!

Did not work for me!
This may work for new oil stains, but the stains I had were old and well soaked in. I put the product on the stains and left it for 2 days when I brushed it off per the direction there was little to no change in the stains.

I followed the directions and it did not remove the oil stain.
