One of the projects I have planned for this spring is to clean my garage floor. It's in great condition, but it has a few oil stains and dirty spots I would like to clean up.
The floor is only a few years old, and has a very nice troweled surface. So, I don't want to use anything that will etch or damage the concrete. I just want to clean up the stains and dirt.
Any recommendations other than the basic soap and water?
This suggestion from my mechanic has worked for me: Tide laundry powder. Sprinkle some on, and mist with water enough to make a paste. Scrub with a brush, rinse, repeat. The rinsing may be a problem for you, if the floors not angled so the water heads out the door. But, if you can manage the rinsing, the method works fine.
Thanks, I'll give it a try. Rinsing shouldn't be a problem. My floor is sloped, and I've hosed it down many times. What little water remains I can sweep out, then let air dry.
That's like saying "why clean house, it'll just get dirty again". :)
It doesn't have to be perfect, I just want to clean up the majority of the mess. We rarely park our cars in the garage, I use it mostly for woodworking and other projects. So if I can get up most of the oil and dirt, I'll be happy.
The point is that if the stain has soaked into the cement, you won't be able to remove all of it unless you want to try a jackhammer. What you will be able to achieve is eliminating what's on the surface. I do it so people won't track it in on their shoes. If appearance is your main goal, it's time to deal with the cause of the oil stains (proper car maintenance, sloppy oil changes, etc.)
Getting it really clean is not an easy project as it soaks into the concrete.
I like the Tide idea, at least give it a try first. You can also find materials in the hardware store make for it. I use kitty litter to soak up as much as possible then add more kitty litter and Naphtha. Let the kitty letter absorb it and repeat a few time.
That's what I was wondering. I don't recall ever seeing concrete cleaners in the stores. Any stores or brands you would suggest?
Yep, same here, as soon as I possibly can after the spill occurs.
On some of the bad spots, I'll spray on a generic degreaser and cover with kitty litter again. Usually gets the worst out.
I've also found that the fine saw dust from my woodworking helps soak up a little bit too.
We don't park our cars in the garage unless I'm working on them, which lately has been to fix some annoying leaks. :) Unfortunately, it's not always possible to get a drip pan under the item that is leaking (like the power steering hoses I just replaced). And then there's always the unplanned "surprise" spills. So a few spills are unavoidable. I try to put a sheet of cardboard or something down if I anticipate a messy job, but again, some spills aren't planned... :)
Kirkland Laundry Detergent from Costco is way cheaper and works well. You can buy a huge tub for something like 12 bucks and it even includes specific instructions for using the stuff on oil spills.
Not for everyone- heat the oils spots with a propane torch. Not too hot or it'll flake off, sometimes with quite a pop!
Really not for everyone- soak the spots with flammable solvent for a while, when it has wicked down add more, add a bit more and light that sucker up. It won't get hot enough to spall the concrete, but it will get hot enough to wick the oil-solvent mix up from a little below the surface, and it'll burn right off.
Or use a coating that doesn't absorb oil. I highly recommend two part epoxy, sold as an industrial coating at most real paint stores. Avoid anything sold at the big box consumer stores. Also note that concrete sealers and stains are not the same thing. Also note that basement floor paint will not work - the heat from the tires will lay nice tracks the first time you drive on it.
Two part epoxies are avilable in most any color including a light grey that approximates new concrete.
In addition to my first message I might suggest that once you get it clean, a top quality true epoxy garage floor paint will make future cleanups much easier. Note: unless you are willing to do a lot of work properly prepping the floor and use good materials, you are wasting your time and money.
Thanks, but it's not that big of a deal. I sprung for a $5 box of Tide. :) I'll have to see how it works when I can find the time on a dry day.
I may consider epoxy a few years down the road, but for now the floor is in great condition. It just needs a bath.
Heres a list of things that clean really well oil from concrete.....

I have a friend who had oil get on his preetty new driveway, from a tree pruning truck that pulled in his driveway.
He went ballistic, the insurance company for the tree guy paid various contractors over a grand for pressure washing and all sorts of attempts by finally 3 different clean up contractors.
The marks are still there 5 years later, and he took it to court. By the time of the trial other drips had occured and the case got thrown out. No doubt the lawyers mad a mint:( Judge visited the home owner wanted new driveway.
His experience was like mine, concrete is porous, the oil gets in the pours and will not come out. Perhaps thompsons water seal right after concrete is new would help. although that darkens concretye just like oil does.
Two words: KITTY LITTER. Buy a bag of the cheapest kitty litter you can find. Pour a handfull on the grease or oil spot. Mash it around with your shoe until it turns to powder. Sweep and repeat. No chemicals, no flames, no water or rinsing required.
In my experience, some brands work, some don't. I suspect the first one I tried successfully was the same stuff as Oil-Dri but I forgot the brand name. :(
