ACTConcrete Cleaner – Eco-Friendly Dry Powder Oil Stain Remover for Driveways, Sidewalks, Garages & Commercial Use | HOA Approved | Bioremediation Formula | Safe around Pets | 8oz

We had a large dark oil stain on our drive way. I applied this product once and after a month, it had lighted a lot. I will put it on again and hopefully it will go away. This worked better than the various soaps, and washes that I have tried in the past on this stain. Happy Camper

I purchased ACT to treat a stained area of my basement cement floor. When the product arrived, I was surprised by the size of the container. It was much smaller than I had expected. Unlike the large container shown in the stock video, my container was only 3 inches tall. Despite my initial concerns, the contents were sufficient to treat my stained area, which measured 5 feet long by 3 feet wide, in two separate 3-week applications.First, I sprinkled the powder over the stained 5-by-3-foot area. Then, I activated it by lightly misting it with water using a spray bottle. The instructions didn’t specify only one mist to activate the microbes, but I decided to spray the floor with water every day. I noticed that the powder dried out very quickly after each misting, and I thought misting it every day might help the microbes stay active and work more effectively. I continued this daily misting routine for three weeks. At the end of the first three-week period, I removed the powder and washed the floor with water. The stain had improved somewhat, but I wasn’t fully satisfied with the results.I decided to repeat the process. I applied a fresh layer of the powder to the same 5-by-3-foot area, activated it with water, and resumed misting it daily for another three weeks. After this second round, I removed the powder and washed the floor again. The results show a significant improvement in the appearance of the cement floor. While it’s not perfectly restored to its original state, the stain is much less noticeable compared to the before.In summary, despite the surprisingly small 3-inch container, the product proved sufficient for two 3-week treatments of my 15-square-foot stained basement floor. My daily misting routine, though not part of the official instructions, may have contributed to the positiv outcome. The floor now looks much better, even if it’s not flawless.Ali Julia reviewReview of ACT Concrete Cleaner

This stuff works !! I have an older truck that was leaking oil for years and oil stains were embedded into our concrete driveway. Dawn Dishwashing Liquid, bleach and other cleaners were not touching it, even with the pressure washer. So now that we got the truck oil leak fixed, figured I'd give this powder a shot. I took a spoon and sprinkled LITTLE of this onto the spots. Then used a soft bristle paintbrush to spread the powder s-l-o-w-l-y and l-i-g-h-t-l-y one way, then the other way like it said, like I was painting. Then I took an empty cleaner spray bottle and on the "mist" indicator, lightly sprayed the powder. When I was done, the oil stains actually looked worse than what it was. But, ok let's see what happens as it said to be patient. 4 hours later, the spots were gone - like magic !! Unbelievable !! We were impressed ! Well worth the price and the effort. Easy to use. My only regret is wished I found this stuff earlier and saved headaches, $$, effort trying to rid the oil stains. Thank you for such a GREAT product !! Keeping some on hand as husband is always spilling something on our driveway. Very satisfied after only ONE application to get oils up after baking in the hot Florida sun.

I bought this as we are renovating a half bath . I used after taking up 40+ year old tiles , toilet and vanity sink. It did work removing odors and stains. It did not clean the concrete to perfect condition, but I felt it did make a great difference. I was able to paint walls while it was on the floor doing it's job. I would buy again to remove odors on "biohazard" stains. For me- it's too expensive to use for just cleaning concrete.

Having some experience in this approach to oil stain management, this worked the best over others I've tried. I also wasn't surprised at the size of the jar when it came, as I imagine some might be. Don't let it discourage you; a very little goes a long way. Just slightly tip the jar and sprinkle a little bit over the top of the stain, and spread with a broom. It may seem like an insufficient amount was applied and you may even see oil saturating the powder, but just wait. In a day or two you'll see a dramatic difference. The bacteria eat the oil, emit a non-toxic fart and die. You may find it interesting the microbes were discovered at the bottom of the Mariana trench, the deepest part of the ocean. In Texas where it's often humid, no water misting was necessary as per the instructions. I don't know why people often think Texas is dry and arid, after all we do have an ocean on our border. The moister in the air activated the microbes. Yes, it's probably overpriced due to its awesomeness but still a great method of handling oil and petroleum stains, which in my book makes it worth the cost.

These were oil stains and now they are ACT concrete cleaner stains.The stains don't look like oil anymore they just look like different colored gray stains.I'm sure it is just a bunch of mumbo-jumbo crap about eating the oil. Don't buy this stuff. If you have oil in your concrete you have oil in your concrete live with it.

Did not work as advertised. It was easy to use but after using the whole jar (very small)..the concrete is still the same. It seem to work...but a few days after using it it the concrete was back to looking like it did before. Waste of money.
