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.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

17 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

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

POST 2Original post

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. -Shawn

POST 3Original post

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.

POST 4Original post

Brake cleaner and kitty litter does an ok job.

POST 5Original post

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

POST 6Original post

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.

POST 7Original post

+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.

POST 8Original post

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...

POST 9Original post

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.

POST 10Original post

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.

POST 12Original post

Kitty litter leave over night then try cleaning the stain. But kitty litter is a must for oil spills.

POST 14Original post

I guess more importantly, how is the car doing?

POST 15Original post

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

POST 16Original post

powder laundry soap works good after it sucks up the majority add a little water and broom around Gas also works and if you close the door while doing it you can get a good buzz on

POST 17 / ORIGINAL POSTEROriginal post

Quotes source post: 9855881

Thank you all for the advice and recommendations, what a great bunch of people we have in this group. Immediately, as soon as I saw the spill, I rolled the car foward and poured a bag of kitty litter and let it sit for several days. In the photo you can see the pile of kitty litter. The car is in the shop and we are going to lift it today and what the damage is and I will post it here later today. One of the saddest experiences is to see your Porsche on the back of a tow truck
