Overnight Stain Remover for Cleaning Oil Stains on Concrete, Driveway, Pavers & Garage Floors,White, AOD3232301

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

Had 25 year old oil stains that were stubborn. Spread this on the dark spots. Let it sit for two days and nights. Swept it up like dust. Removed 90% of the stain. Ordered one more bottle. Will wait a few months for any oil deep down to surface and attack one more time. This product does work very well. My stains were worst case scenario. Two bottles will do the trick, just wait a while before 2nd dose to get all the sunken oil.

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 product was fantastic so easy. I had fresh oil stains maybe a few weeks to a month old on an asphalt driveway I live in a complex so you can't have stains I tried liquid Dawn didn't work I got this stuff fantastic. Easy to use stains are gone. It's a little hard to see that the stains are gone because my driveway is wet I rinsed it off really well but it's off they're gone
