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.

Works well. Make sure you give it a full 12-14hour drying time to get best results. I had an accidental spill of car motor oil on my brick driveway. Regular degreaser did not remove it, so I decided to try this overnight formula instead. It fully removed the stain in one application. After letting it dry overnight, I used a firm brush to remove the dried product, then followed up with a strong pressure wash to remove the white residue. 5 star review from me.

I don't often submit reviews unless the product is very good or very bad. Fortunately, this product is VERY GOOD. After taking bacon grease in what I thought was a safe way to carry it out to a trash can in the evening, I found out the next morning that I had dripped splotches of bacon grease all along my front entry sidewalk. I used AI to get recommendations to remove the bacon grease. One of the many suggestions was Overnight Stain Remover. Wow, does this stuff ever work. Following the directions, I applied the product to each of the grease spots (probably 40 in all) and let it set overnight. The next morning I used a stiff brush on a long handle and swept up the product that had lifted the grease from the sidewalk and then used a garden hose to wash everything down. Thankfully, there is now no trace of the ugly grease spots.

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 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.
