oil stain can't move!!

[ddc]

I have an oil stain i can't move, I have tried lots of ways and it won't even get lighter.
The concrete is very porous but the stain is only about a month or two old. I have tried acid based degreasers and a number of other things, nothing works so far.
Anyone have any advice?

Thanks in advance

Rod

have you tried Citric Acid based?
Or Di-limonene?

Semtex will always work, but some clients complain about the downside.

cleaning

Use aluminum brightener or muratic acid, use surface cleaner to edge evenly and seal or don't park there again. If shadow is still there try dynamite since nothing else will remove it.
