Great on removing greasy spills on patio pavers -- if you use it right away.
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.

It works as advertised.
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.

Works Pretty Well!
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.

50/50 for engine oil stains…
I read the AI overall review and I agree. Sounds like we all have a mixed opinion. In my case: old oil car stains on driveway. I did one side and compared it. The stains did NOT go away, but i can see lighter oil stains where I used this compared to the existing stains. I will give this another try….

Awesome Product...
Simply put, this stuff works...I had several oil spots on my driveway. followed the instructions, next morning brushed it off. stains gone. I will say my oil spots were only about a month old. If you have oil spots that are years old, not sure how it would work. This product is $4 cheaper than Chomp, probably the same ingredients. Easy to use, go for it.

It WORKS ! ! ! ! !
Works BETTER than anything I have tried. Tried Goof-Off, Gasoline, Dish Soap & Water, High Pressure Washer, Muriatic Acid, Floor dry /Bituminous Clay and lots of elbow Grease. One application, dried overnight, Brushed off the next morning - and 'Voila' oil stains on concrete were GONE ! ! ! I had one small 1 1/2 inc diameter oil stain that I had to Repeat the application and - - - It WORKED ! ! !

Didn't work for me
This product barely touched the small oil stains in my garage. Suggest the reader try Goof Off Concrete Cleaner, available at Lowe's.

Works okay
It works it would probably eat cement if you left it there long enough but it does a trick it's not perfect You're still going to see Mark's where you put it but better than just oil on your driveway maybe gasoline in the scrub brush might work just as well at least according to my brilliant maintenance man lol
