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.

It Works -Amazing, the stains are gone!
This stuff is AMAZING! It worked on the first try. I bought 1 bottles and I was very liberal covering every inch of a few spots on my driveway. I layered it on everywhere, scrubbed it and then evened it out. I put it on after the sun had gone down (I'm in AZ and I was worried it would dry out too quickly). Then things got busy and I probably left it on for 2 days. It took more than one day for every single spot to completely dry out, maybe because I had it on there so thick. The stains are GONE! Completely. I wish I had taken before and after photos. I had done some research on the microbes for eating up oil stains like this and I'm convinced that is the key. You can't go wrong with this stuff - I am a very happy customer!

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.

Bye bye oil stain
Bye Bye oil stain left in my drive way from a delivery van. Still needed to scrub the stain but sure did a great job in breaking up the oil.

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.

Amazing product!
I hardly ever write reviews but after using this amazing product I felt compelled to. I had oil stains on my pavers. I applied the product waited 12 hours then brushed the residue off. Then I washed the pavers with my garden hose. The stains were completely removed! Incredible!

This stuff actually works. Be sure to allow it to completely dry.
This stuff actually works quite well. I probably use too much on each oil stain, so I'll reorder some more and be more careful about pouring it on whatever oil spot on my unsealed concrete garage floor. Eventually I'll seal the garage floor, but to make the sealer adhere, I want to get rid of all the oil stains. I'm a home mechanic that maintains three family vehicles and an oil spill is difficult to avoid. I use an oil dry product that removes the bulk of the spilled oil, but I feel I need to remove it all to make the sealer a permanent protection to my garage floor.

It didnt work per instructions
Didn't work for me when following the instructions . But when I tried scrubbing it with a wire brush while wet it worked alot better but still can see some oil stain. But when I let it dry and brushed it off it didnt do anything on old or fresh oil stains. When I tried it wet on the old oil stains it didnt do anything. The oil stains in the picture i used it on all the oil stains and let it dry . The one little section i used wet and scrubbed it with a wire brush so if your looking for a quick easy solution this isn't the stuff

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