Review on 🧼 EXIMO® Waterless Concrete Cleaner (0.75 lbs) for Drive, Garage, Basement, and Path Surfaces, Advanced Stain Remover for Oil and Other Petroleum Stains by Stephanie Roberts

Works on particularly heavy oil and grease stains. The work is still ongoing. A downside, however, is that the powder is almost exactly the color of concrete, steel gray. That's good because it hides the stain while it's being worked on, but...well, it hides the damage you're trying to fix, making it hard to tell how well it's going. It also tends to turn into a kind of semi-hard crust over time. I couldn't shake it off, so I had to use a pretty high-pressure jet of garden hose. It took a lot of work to get it to peel and flake under pressure. Finally got most of it removed - and yes the blemish is down 65-70% but still there and still needs work. Which in itself isn't a criticism of how well this works, as we know it takes time for the bacteria to digest the carbs - you can't rush love or anything like that. The problem is that if I didn't know he created this "crust" I would think he almost completely got rid of the stain. At least that's what others thought when they saw it. Again - great that it's hidden and frustrating that it's difficult to monitor progress. All in all - if you're patient and not in a hurry to fix the problem, this is an eco-friendly alternative to a bunch of bad solvents. and cleaning chemicals that inevitably end up in driveways, drains, sewers and waterways.
