Concrete Stain Remover

After trying all the natural ways ( i.e. dish detergent, baking soda) to remove the recent 3" oil stain on my new paver driveway, I was ready to give up and accept that it was permanent. Then I read the reviews on several commercial products and settled on "Overnight Stain Remover". It took 3 applications, but each time the stain reduced in diameter and depth of discoloration. I've attached 3 photos. I didn't take a picture of the original stain, but the first picture depicts how it looked after the second application of the product. You can see a faint outline of the original stain in that first photo. The second picture is the third application. The third is how it appears now. I might apply it once more to pull out the residue, but it blends in with the rest of the pavers, it's hardly noticible. I highly recommend this product.

I had a motor oil stain on my paver drive way that came from a bag that leaked where I disposes oil filter. This stain was stubborn and nothing got it off I tried power washing, dish soap, good off , nothing. Over night oil eater worked very well the chalky residue is even less noticeable in person than this picture. A few things you NEED to know that not all of this was listed on the bottle : You need no rain for the following 24 hours (I think the bottle says this) . What the bottle doesn't say , is you need temperatures to preferably be 60 degrees or better for it to dry properly and you need to apply it over night. This happened to me in March in the northeast, I had to leave stain for a few weeks until we finally had a night where the temps stay 60+. You also need to do this overnight because all day sun is bad for it. I asked the company this because I was thinking can I set it during the day when we had 70 degrees days but cold nights and they said it went work it's best. Also, you NEED to let it dry fully and become a full dry chalk like substance. I wound up letting this sit 24 hours, slI applied it at night, but the following morning some spots were still gel like , so I let it sit all day , since most of it was dry and I fogured the sun couldn't hurt it while it was drying. After it dries, scrub it off with a god brush. There will be a big chalk residue that outlines the stain. I left that alone and let it sit further. The company told me don't immediately use water to wash off the chalk. I let it stay a few days then j sprayed it all off with water. This is how the stain looks now. There is some slight chalk outline left but the company states it will fade over time. And I have to say in person it looks even less noticeable than in this picture. The bottle also says for severe stains multiple applications might be necessary so I might do it again. So the keg take aways because I know this product got mixed reviews - you need to use it in ideal temps and make sure it dries fully .

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.

This stuff is magic! Completely removed an oil leak in my driveway overnight. This product dried super fast and was easy to remove. I took a before and after picture and had a hard time finding where the stain originally was. You can see a little bit of the white residue but I'm okay with that!

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.

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.

First time spilling oil on the garage floor. Cleaned up what was there. I was skeptical about this product. Ordered, received it quickly. Followed the instructions, placed on oil stain. Following day swepted it per instructions. Oil stain was gone. HIGHLY RECOMMEND OVERNIGHT STAIN REMOVER.

This product was recommended by a relative so I decided to give it a try. It is a white, slimy lotion out of the container, then spread it on the oil stain on the driveway. Leave it to dry and then use a stiff brush to scrub away the white scab that becomes a white dust when scrubbed. One very minor complaint is that there seems to be a lighter "stain" on the driveway on the treated area that looks like new concrete. It goes away after a good rain, which we haven't had much for months. In summary, it works and I would buy it again. One final comment...4 stars is very good review! I generally don't give anything 5 stars for anything as that strikes me as being perfect and nothing is perfect, me included!

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