stained concrete
 

does anyone know how to lift out oil and transmission fluid stains out of concrete? or can you paint over them with anything? I've tried just about everthing and no luck:pimp:

Tell us what you've tried first so we don't end up wasting your time with alternatives that haven't worked for you.;)

try a high pressure washer that heats up. It always works on greasy motors. Then coat the concrete with some sort of sealer so it's easier to clean next time.

I use carb cleaner form Walmart. $.84/ can !! And a few rags.

Use a cloth mop and kerosene. Then put some dry sweep (cat litter) down and sweep the area off.

Another thing you can do is after you have mopped the area, sprinkle some dry mortar and sweep it off. The only problem with using the dry mortar is that that area will look better than the rest.

I should have been more specific, I don't remember the brand name of what i used but I have gone to the local stores and tried everything except acid etch, everything from 5 to 35 bucks now that don't sound like much but this is good for about 5x5 area,, but nothing i have used even starts to lift it thanks for the input there has to be something out there so if anyone knows of something I'M A LISENIN

I use gasoline and then kitty litter type absorbent (diatomacious earth available at auto parts stores). Works great but VERY DANGEROUS! Don't do it in a garage w/ a water heater!! Maybe paint thinner would work and be a bunch safer. Less aggressive solvent than gasoline so let it soak a little longer B4 applying the kitty litter. Point is use an aggressive solvent that will penetrate deep into the cement, totally dissolve the oil, then use the kitty litter to suck it out. May take a couple of treatments for heavy oil contamination but works really well.

I use electric motor cleaner or brake cleaner and then as quickly as I can I toss some cheap cat litter to soak it up. The cheaper the litter the better.

Kitty litter and do the twist.:thumbup:

An old guy once told me (and I have yet to try it) to mix some corn starch, powdered laundry detergent and kitty litter together and just let it sit for a day or so. You will never completely get rid of the stain, but it will be much better.....

First put some Dawn dish detergent on it and let it soak, then use Tide laundry soap, sprinkle it on and use a wet brush to scrub the area then rinse.

I tried a container of Snap-on Dry6 spill absorbent. Stuff works awesome. It was right around $10 or $15 for 13 oz. so it's not overly cheap but it's better than anything else I've ever used. My local Snap-on guy said that it was something that didn't sell real well, but I bought him out anyway. They've also got a new floor cleaner listed for $49 for 20lbs. I'm not sure how good it is, but I'm sure I'll try it in the future.

i usually cover the stain with the car, seems to be unnoticable:thumbup:

HEY RED: In the latest issue of Car & Parts magazine there is a whole page story about a new product guaranteed to clean concrete floors. If you send me a FAX number or mailing address I will send it to you....GOOD LUCK...DAVE

that's what i do, pulls most stains decent
