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.

This stuff works better than expected! Just follow the directions. It really does just brush off when dried...its that easy. Can't believe this has bee around a long time AND is USA made!! I will definitley buy more when needed. I had a rather large OOPS of used auto trans fluid on a newer concrete driveway. This worked great!!

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.

I’m not mad. Quite frankly, I think this could really work. Context my oil stain is beyond saving. I have been leaking oil in a large spot for about five years. I wanted to do a last ditch effort on trying to clean it. Before seal coating it. It does leave a white residue which comes right off. You can see this stuff working. If you give it the time that it really needs to do its job I could find this very effective. I ended up purchasing two bottles. I poured the first one on the entire spot the whole bottle. I let it sit for two days. It dried on the edges and you can literally see it, pulling the oil up and trying to do something with it, but there were so much that it had nothing left to itself to convert it. I purchased the second bottle and applied about a quarter of it to where there was significant oil. It then converted some of that in the white edge got larger once I saw that was no longer converting. I poured some more on and so on and so forth. I definitely would have needed multiple bottles maybe five and I don’t think my spot would have completely come up. I do think this significantly significantly improved the look of my horrible oil ruined driveway. I wore a glove for safety and spread it with my hand. It does say do not get it on your skin. It doesn’t smell bad or good. You shouldn’t smell chemicals though. Application was extremely simple consistency is very liquidy and then literally dries nothing more than a shop broom needed to get this up. I would say definitely wear a mask when you are sweeping this up. I don’t think it’s very safe to breathe in, definitely put me into a coughing fit. See below for Before And After pictures. I did switch over to another powdered brand that hardens the driveway I don’t have a ton of time to continue with this, but I do think it could work on your oil stain. You really need to see the Before and the after given that the after pitcher is wet, but it has significant improvement. I would say the hotter it is the better let this sit for days! Keep an eye on it, revisit it put the work in.

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