A sodium hydroxide based degreaser should do the trick. As always read the labels for all safety info.
If you need more specifics call or email me.

This is what I do

Being that I clean Vent Hoods also. I buy like 100 pds at a time of caustic bead in 25 lb bags. about 105.00 bucks.. I wet the concrete wher the oil is and then sprinkle caustic bead on it. The caustic bead soaks up the oil and then I rinse .. with hot water.. Works like magic.. and caustic bead is cheap about $1.00 per pound and an average cleaning of concrete only cost $ 1.00 in chemical .. And $ 8.00 in fuel..

In conjunction with the sodium hydroxide based degreaser I would also use Armex Blast Media (Sodium Bi-Carbonate). If you require any further information please e-mail me.

Hey john how long do you recomend letting the caustic sit on the stain?
I tested this out on my driveway. i had some bad brake fluid stains that were about 6 months old it got them a lot lighter but they are still there. i used cold water and 3000 psi.

are brake fluid stain harder to remove than oil.?

 

[Russ Spence]

you need a strong solution and let it dwell,then you really need hot water to finish

 

[K Gauthier]

is it possable to get it out with cold? how strong of caustic mix do you suggest if you were using cold water?

where can i buy caustic beads and can it be used for multi color brick driveways, walks, etc.

 

[Russ Spence]

I use it on concrete only , it is a very strong cleaner and I personally wouldnt use it on anything else
