Concrete Stain Remover

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.

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!

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.

Used in garage to treat oil, power steering fluid drops, about 1 year old. It did make the surface cleaner and it felt less greasy. But did not take color away as expected.

this stuff does a great job of removing greasy spills on my patio pavers, as long as you put it on early. If you wait a day until the greasy stain dries, it does not work so well. But, catch the spill early and works very well.

Our concrete pavers were stained with oil from an A/C compressor coil leak 3 years ago. We just replaced the entire system, and the new outdoor compressor is an upright front discharge unit with a much more compact footprint than the old top discharge unit it replaced. The stain that was under the old unit was suddenly really visible, and I tried all the "home" remedies first including sand, laundry detergent, toilet bowl cleaner, power-washing -- and none of them really did much to remove or even visibly reduce the deeply set stain. Overnight Stain Remover has almost removed the stain after two applications. Each time it looks really good right after use, but then the stain comes back. The first time it looked great for about a day, and then the stain started to come back -- although fainter and smaller than before application. The second application again removed the stain, and then after about a week some traces of the staining came back faintly on an even smaller area. Hoping a third application will eliminate the last traces permanently. But even if not, it's faint enough the casual observer probably wouldn't notice it -- and it's so much better than I ever expected it to be given how long the oil had soaked into the pavers. Wish I had tried this first -- would have saved a lot of time and effort. TIP -- works best when concrete it cool -- do it first thing in the morning and keep the hot sun off it (shade with something) if possible. Update: A workman's truck dripped oil on our driveway. One application of some of the leftover Overnight Stain Remover took care of it. Good product to keep on hand for oil spills in the garage or driveway.

I applied it at 50 degrees but overnight it snowed. Needless to say those aren’t ideal conditions for this product. But after the snow melted and I used a metal scrubber the dark oil stains are pretty much gone. Very satisfied customer.

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.
