Help- How To Clean Motor Oil From Concrete

[Kor]

Thinking of painting my garage floor this weekend, but I have a black spot in the middle of the floor from when my Rabbit leaked oil. I also may have knocked over a jug of oil at one point. Anyway, its gross.

Any advice about cleaning this oil up before I paint?

So far I have found out that some people recommend gasoline (dangerous but effective) and others say oven cleaner (I am heasitant to try oven cleaner in case it corrodes the floor).

Not gonna try coke cause its sticky and I know it does corrode concrete. The oil is really soaked in so I think a solvent is best, like gasoline or paint thinner.

Coke corrodes concrete?

There are oil remover products that you brush in with a broom and then just wash away again I think places likely Crappy tire sell them. I would then hit the really bad sports with castrol super clean. That are you going to paint the floor with? Using a primer coat?

I did a search on Muric Acid, as I think that's something I've heard of before. Very powerful (be careful).

Came across this forum that talks about painting garage floors.

Talking technically.... like dissolves like

So oil is a heavy hydrocarbon..... so gasoline might work, but along that mindset, shouldn't diesel work better?

There is Paint for garage floors, it's something like a 4 step process, I saw the stuff at Home Depot, I think it has the stuff for removing all the wax and grease on the floor.

Muriatric acid is probably what you're thinking of and it's pretty good for acid etching and cleaning concrete.
