NATIONAL MFG/SPECTRUM BRANDS HHI FG820 32OZ Goof Off, 32 OZ, Degreaser, Removes Embedded Oil from Concrete, No Scrubbing, No Rinsing, Liquid Dries to Powder, Easy to Use, 32 Fl Oz (Pack of 1)

I was a little apprehensive at first. My oil stain was about two years old and was quite large. I had previously tried to power wash the stain but was unsuccessful. My powersprayer is a a cheap electric model. I applied the thick liquid and lightly spread it evenly over the stain. I let it sit for 24 hours and then used a push broom to remove the dried powder. I then hosed it down and the stain was gone! Super easy to use. Make sure you shake the bottle vigorously for a few minutes before use. One bottle is good for about 4-6 square feet of stain. Let it sit for 24 or more hours.

I followed the instructions and my driveway oil spots are about 95% clean 👍🏾

Definitely faded huge oil stain in my driveway. Left in on for 24 hours, then used push broom to scrub and hosed off. Would buy again. Took 3 bottles for my driveway.

Worked well on old set in oil stain on driveway

First off, I knew I needed to transfer the liquid over to a different squeeze bottle for more application control. I shook the OEM bottle very well and used a funnel to put it in a 1.5 Liter squeeze bottle. When all the liquid was transferred, the Goof-Off bottle was still heavy. I looked inside, and there was about 1/3 of the bottle filled with what looked like wet clay. Transferred the liquid back, and shook the heck out of it again. After transfer, I still had material left in the bottle. Well, after the 4th time, I managed to empty the original bottle into the squeeze bottle. Bottom line, really shake this stuff before use. Then shake it again.As for the application, it does get out most of the oil stain, depending on how fresh the stain is. It looks a lot better than it originally did, with a combination of older and fresh oil stains. The older stains are still visible, but much lighter than they were. It did about what I expected, we'll see how it looks after I pressure wash the area.Frankly, I would think a better use of time would be to fix whatever the problem is with your car or truck or whatever to keep it from leaking oil in the first place. My wife's car does not leak oil, but it's an awful mess to change the oil, no matter how big of a drip pan I put under it. My car was leaking oil from the camshaft position sensor, which is hard to see. Replaced the CPS, no more problem, cost about $25 to replace the part. No oil on the driveway is much better than trying to clean up the drips. This stuff helps, though.

You just pour this on the oil spot Brush it in let it sit for a couple of hours. Brush it again before rinse. I let the concrete dry before repeating the steps. It took a whole bottle, but it worked.

I watched several YouTube videos on this product and applied it to several old oil stains inside my garage. I followed the instructions on bottle with little improvement, then I poured it directly from bottle on stain and evenly spread it.... Let it dry.... And came back the next day with wire brush.... Better results.The best results was I put about 4 oz mixed with 32 oz of water ..... Sprayed it into the stain to it puddled up and then I scrubbed it with a wire brush while still wet .....let it dry to a chalky residue.... Then wiped down the area with a wet shop towel..... Won't remove stain , but will fade it

I tried multiple products, but this was the only one that actually worked. I used it full strength and let it dry then rinsed it off.
