I’m a gear head and am always working on a car or tractor it would seem. Like many, I have a concrete drive way and it seems like no matter how hard I try, I get engine oil, grease, gas or whatever other crud on the cement.
I’ve seen guys post asking about how to get oil and what not out of a cement drive way and I have a simple answer – I use a degreaser called “Purple Power”. I know it is a crazy name but it works. I’ve been using it for probably 10 or more years and buy it by the gallon jug at Autozone. I can’t recall who recommended to me or just when – but I’ve used it for a long time and vouch for it.
My approach is simple:
- If you have standing oil, pour clay cat litter or oil absorbing pellets and let it sit for a few hours to a day and then brush it up and save it to be used again. We don’t have cats so I usually just keep a big bag of the oil absorbent stuff from Autozone and use it over and over until it gets real oily. I just keep it in an old pail.
- Pour on the Purple Power full strength and let it sit 15-30 minutes. I would recommend doing it in the morning or evening because you do not want it to dry out.
- Use a hose with a pressure nozzle (just something to focus the spray coming out of the hose) and rinse the stuff off.
- Let it dry and see how it looks. If there is still some dark spots in the cement, you may need to do it a couple more times. For me, it usually does the job in two passes but sometimes I need a third.
Okay, here’s a photo of my drive way after working on a car and a tractor. The big “blotch” is a combination of gas and oil. I changed the fuel pump on my tractor and then cleaned the engine up with brake cleaner and it went on the drive way. The four smaller blotches to the right of the Purple Power jug are soaked in oil from working on the car.
This photo is after three passes with Purple Power and letting it sit 15-30 minutes each time. If I had done it a fourth time it would be even brighter but I literally ran out of cleaner. You can see the big blotch is entirely gone. Really, just a bit is left. At some point this weekend, I’ll run up to Autozone and get another gallon and finish the job.
If I didn’t use Purple Power, my driveway would be an absolute mess. I go through about a gallon per year sometimes two – it just depends on what all I am working on and how often I clean up my driveway.
I hope this helps you out!
