Heavy Oil Stain

[JamesV6CDX]

I'll keep this brief because it is what it is ... I have made a balls up and kicked over a bucket of used engine oil from my 3.2 project, all over my concrete driveway. Up to three litres spilled. Covered in compost (all I had nearby) to stop the spread, I later removed this and went and got some cat litter which soaked it all up, but (obviously) has left a big (big!) black stain. Let's say half a meter square - significant.

Someone on OOF must have been in this position before  Any tips on removing the stain, please? It's grey concrete, not tarmac.

Cheers 👍🏻

From Google.  Not sure if it works.

Oven cleaner can be a very effective treatment for oil stains on concrete. Simply spray the target area with oven cleaner and let it settle for ten minutes. Use a hard bristle brush to scrub it clean and rinse with a hose. Repeat the process until the stain is removed

Oven cleaner
baking soda
dish soap

I reckon its a womans department as all the materiials are in her section of the house.

Sorry to hear James has kicked the bucket, he was such a nice, helpful lad 

[Marks DTM Calib]

Nothing will remove it all as Concrete is porous and it soaks in, cement may pull a lot of it out

I've had reasonable results in the past with Gunk driveway cleaner .... but it was only small stains ... not a bucket full of oil.

I inherited some triplewax jet wash driveway cleaner that took the oily residue of a small spill off a black driveway very easily.

I reckon your best bet is to cover the rest of the drive the same, then it will all match.

[Viral_Jim]

Maybe better pulling the majority of it out with the above methods then treating the whole driveway with something so it all matches...


Have you got any more used engine oil? 

[JamesV6CDX]

I didn't expect any serious responses 

I doubt it will clean out. I'll try but I doubt it.

How big a deal - or costly is it, to have it concreted over or similar to rectify it? Cheers

You mean once you've dug it out and relaid it?

A screed will never stick to it. Nor will any other coating.

Detergent, steam and time will mitigate it, but the only way to actually remove it is with a chisel.

If that's what it takes then fine ... just after an idea about what's involved and what it's likely to cost. It's not my bag and I am totally fine with that. I will need a man who can

[Doctor Gollum]

Cost will depend entirely on depth, area and type (density/composition/reinforcement). That said, if you're only talking a couple of square feet, it should be pretty diyable

Sounds like you have a 'make good' lease

F*ck me, you're a builder now as well....?
