    Would you expect there to be any difference in oil cleaner response between mineral and synthetic oils? Intuition says no but a small question mark is rattling around... would the chemistry be different in any key parts of the synthetic oils response to a cleaner ?

    A liberal dose of mineral turps thins the oil and allows it to soak down into the concrete. Does leave a slight carbon stain from diesel engine oil.
    Caustic soda, (sodium hydroxide) solution will turn oil to soap allowing it to be washed away with water. There are some degreasers that work this way.

    I use hydrated lime on our pavers, it's not a quick solution but it doesn't stain or set.
    Same reaction as cement powder, fine powder draws the oil out and the PH of the lime will make a form of soap.

    OK a few responses since I last checked.

    What I've done so far.

    A bottle of CLR grease etc remover (what used to be called liquid magnet).
    Left on for 5 minutes then scrubbed for 5-10 minutes then hot water applied, then hosed off.

    Then detergent in hot water - left on for a while, scrubbed, hosed away.

    Same again using car detergent.

    Same again using 1/2 box of laundry detergent.


    Effect so far evidently nil.


    The driveway was sealed with something (no idea what) when built but I don;t have any confidence it actually did seal anything properly.

    As far as cement powder is concerned - that'll harden into a lump if it gets wet so surely not a good idea?
    It's not broken. It's "Carbon Neutral".

    You're looking for a bit of instant gratification with those timelines.

    Try again with plastic over the top to stop evaporation and leave whatever for a couple of days.

    he needs some nice old hydraulic Citroens scattered about the land rovers. The nice green puddles of hydraulic fluid everywhere blend in nicely with the puddle of gearbox/steering box/engine/diff oil from the land rovers

    It also trains wives they will NEVER have a nice clean bit of concrete anywhere .... well ever .... So its simply not worth worrying about

    Mate I'd love a DS Citroen but the missus thinks they are the ugliest car ever made.

    When I spill oil on my shed floor I soak with petrol then put lots of newspaper to soak it up. Sort of works like blotting paper.

    Many years ago I used white king on a driveway with good results.

    You could also try this CRC Oil Eater - Oil Stain Remover for Driveways, Paving, Timber and More! - YouTube

    I was asked " Is it ignorance or apathy?" I replied "I don't know and I don't care."
