I remember seeing a thread about removing stains from concrete not too long ago and should have paid more mind to it. I have a situation where a dumpster was sitting on a driveway and once removed, a nice grease stain was sitting under it. Unfortunately, the homeowner chucked a gas grill before the dumpster was hauled, and the grease from that is what is left on the driveway. Can anyone tell me what would work on that kind of grease staining and if the techniques for removing it are any different than indoor removal. Thanks for the help.

I have tried using engine shampoo on black oil stains with good results and used good old fashion lye works well .Scrub them well with a deck brush.

Hi, the best system I've used is to sprinkle Portland cement on the stain, let it set for a couple of days and then sweep it up. This works real well for motor oil or heating oil although you may have to repeat the proces several times. A real estate agent showed me this trick. By the way, if you have tiny cracks in your concrete floor, sprinkle the cemeny on it ans sweep it around. The cracks will dissapear,for a while at least. Now why would a real estate agent want to do that?

My suggestion is a solution of hot water and trisodium phosphate (TSP). You can get TSP at the hardware store. It is intended for this type of cleaning.
To use, scrape the surface grease off first. The use the solution with a stiff broom.

My way works better and with little or no elbo grease. Grease and oil stains wick right up into a rag. The problem is that I can tell ya. The EPA might get me.

For oil and grease: gasoline and kitty litter.

Barbecue? This is animal and cooking grease, right? Cooking grease will saponify under soap attack. I'd scrape off the worst of it and go after the residue with dish detergent and a stiff brush.
Kenh, give that gasoline trick a break will you? It's not only far too hazardous but other higher flashpoint petroleum solvents wrok as well or better. Maybe you're joking, I don't know. I can't tell. Regardless I'm sure you would hate for an accident to happen subsequent to someone following your suggestion.

Pressure Washer. I cleaned my 50 year old deck, garage floor, and sidewalks with my 13 hp pressure washer and it took out stains I never thought would come out. I had tried the kitty litter method, and a couple of checmical cleaners, and the pressure washer did the best by far.

If it's just from a grill then it's just grease and soot. Soap, water and a brush should do.
If it's from whatever else might have been thrown in...
Scrape off what you can. The set in stuff in the concrete, including rust from the dumpster, can be removed with plain old muratic acid... brightens, whitens, removes stains. Home improvement stores, masonary or pool suppliers will have it in gallon jugs. Use a 50/50 mix with water, for really tough stains go full strength. Use a brush and pail to apply, let it do its thing then scrub it a little. Be sure you have good ventilation, the vapors are irritating. Copious amounts of water to rinse.

With time and a few rains a dry sprinkle or liquid clothes washing detergent applied will make stains go away.
A fellow I met last year was moving to Florida and proposed that he was going to start a service business cleaning driveways. Never got a follow-up on how that plan worked. He left from a successful lawn service here in Michigan
