My car suffered damage from a speed bump and it poured 9 and a half quarts of oil on the garage floor. I tried to remove the stain with several products including one from Auto Zone that was worthless I thought that I would post here and see if one of my fellow RL'ers could offer some good advice. Any and all advice and suggestions are appreciated

UPDATE:It appears that the culprit is the oil pan. Nice big 8" crack, enough to release all 9 quarts of Mobil 1. Having trouble finding one Any suggestions where I can find one?? Probably a used one would be priced more reasonable Any assistance is appreciated

 

The best results I've had are with undiluted Simple Green and a red/burgundy scotchbrite pad. Even that's not going to make it like new, but it helps a lot.

I went with one of those concrete painting kits from lowes/home depot. Came with a acid based cleaner, then a etching primer then the paint. It has held up well over the last few years.

 

Brake cleaner and kitty litter does an ok job.

 

xylene from a paint store may work. We used to manufacture a product that worked great, TK 14, but alas, it was obsoleted.

 

after oil dry, I have had good success with purple power degreaser scrub in with broom then cover with kitty litter/ oil dry again.
Repeat a few times then a final clean up with dish soap.

 

+1 on kitty litter, it's what the police and fire department use when there is an accident on the road to soak up oil and fluids. May still leave a mark, but will get the oil up.

 

I would use Goo Gone. i would let that soak for awhile and then wipe up with paper towels. Maybe do this a few times. Then I would sprinkle Comet Cleaner and water and scrub the area with a brush, rinse, again if required...

 

A product called 'Spray Nine' should get it out. Walmart should have it. Will even lift off nicotine /tar stains from walls and car interiors. I used it on grease and tar stains on my pickup, wiped right off. Spray on and let sit to soak in for 15-30 seconds first. I have used Simple Green as well, it takes lots of elbow grease and won't get all of it off like Spray Nine will.

 

As per John Tesh, a spray of WD40 or equivalent (liquid wrench) on the concrete floor will lift off oil in a minute or two then wipe off with paper towel. I tried this before and it surprisingly worked! Oil spill on my garage floor sometime ago at about 2.5 qts, half a can of WD40 and a roll of paper towel did the job. Some staining but no oil on surface of concrete.

 

+1 on kitty litter

 

Kitty litter leave over night then try cleaning the stain.

But kitty litter is a must for oil spills.

 

Have you considered using a power washer?

 

I guess more importantly, how is the car doing?

 

That is what I was asking myself, forget the garage floor, how is the Porsche?
