CAF Outdoor Cleaning EXIMO Waterless Concrete Cleaner, Oil Stain Remover for Asphalt, Driveway, Garage Floor, Basement and Walkway Surfaces, Natural Concrete Cleaner Powder Treatment, 3 lb Container

I do a lot of hobby car work in my carport, esp. on older cars, which means an accumulation of really nasty oil and grease stains of various kinds. Using typical cleaning products to try to clean this up generally doesn't work all that well, and tends instead to spread the oil and grease, and their stains, without really looking like you've done much to remove them. This stuff is different. First of all, it takes way less time than trying to clean concrete with other common cleaners. You also end up a lot less dirty at the end—there's no splashing, no treading in greasy liquids, etc. There's basically just light-colored powder that's easy to brush off of anything it gets on. Most importantly, it has done a better job of actually cleaning the dark, grimy-looking staining out of the concrete than anything else I've tried so far, and the best part is that there's no mess and no oil and detergent being sprayed off into the lawn or into the drain system. Instead, you just sweep it up. It seems to stay powder-like and light in color, even after having been used on fairly thick and viscous layers of grease. It sort of just magically digests them away. One key point that I've learned as I've used it over the last few weeks—you don't want to just sprinkle it on and then leave it there. I did that for the first couple of weeks and didn't notice much of a difference. Things really took off when I began *sweeping it around* every day. Just about 30 seconds each time with a broom across my entire carport floor. Back, forth, here, there, just manipulate it enough so that this stuff gets all rearranged on the surface. Once I did that, it was only about a week before most of the staining was entirely gone and the concrete is about 10 shades brighter than it used to be. Then, once you're satisfied with where you are, you can just sweep it all up. I have no idea if this can be reused, but it's still in dry powder form after having taken a 1/8" layer of junk off the floor in some places, so I've saved it in a coffee can and we'll see what happens when I have more stains I need to clean up.

Used as the manufacturer recommends and given adequate time and a bit of attention, Eximo works as promised. My wife's old Lincoln had a serious oil leak from bad crankshaft seals. Fixing the problem would have cost more than the car was worth so we just let it leak until we were finally able to replace it. This might have been a good fiscal strategy but it was not so good when it came to the aesthetics of our driveway; the thickness of the buildup was measurable, so heavy that I decided to use a square-nosed shovel to scrape off a layer or two before commencing with remediation. This still left a thick, ugly layer of oil in place for the first application of Eximo, so my hopes were not high and the results of the first application which, per the online instruction video, was brushed on and left dry, were discouraging to say the least. Reading the printed instructions, I noticed that they stated that wetting the powder would speed up the process so after the next couple of applications I used a misting nozzle on a garden hose to wet it down, enough to leave a film of water on top but not enough to wash away the powder or cause runoff. The results were strikingly better, with a significant reduction of staining within days of each application. Thinking that if one watering worked well, maybe even more watering would work even better, I began misting the treated area daily, and got amazing results. The speed of the process increased greatly, with noticeable change every morning. After six weeks, there's still an ugly stain on our driveway but it's size is very much reduced and patches of clean concrete are showing through as I continue with weekly applications. Used dry, Eximo treatment is glacially slow and probably not cost effective. When used with water, however, the stuff is amazing and well worth the price.

Working on an exceptionally heavy oil and grease spot. Work is still in progress. One shortcoming, such as it is, is that the powder is almost exactly the color of concrete, a steel grey. That's nice in that it hides the spot while it's being worked on - but - well, it hides the damage you're trying to correct, making it hard to tell how well it's progressing. It also tends to turn into a sort of semi-solid crust over time. Couldn't brush it off, so had to resort to a fairly high pressure spray from a garden hose. Took a lot of work to get it to flake and peel off under pressure. Finally got the majority off - and yes, the stain is about 65% to 70% reduced, but still there, and still needs work. Which again, isn't in itself a criticism of how well it works, as we know that it will take time for the bacteria to digest the hydrocarbons - you can't hurry love, or something like that. The problem is that had I not realized it had created that 'crust', I'd have thought it had cleaned up the stain almost completely. At least, that's what someone else thought when they saw it. Again - great that it's hidden, frustrating that it makes it hard to monitor the progress. Overall though - if you are patient and not in a hurry to resolve the problem, this is an environmentally friendly alternative to using a bunch of honkin' bad solvents and chemicals to clean it up, which inevitably make it down the driveway, into the gutter, down the sewer, and into waterways.

I am not sure about this product. I watched many you tubes all done by the same CAF . I think ooutdoor temperature is an issue
