It will - but depends if its a few drops on one or two bricks of over a larger area..
Many years ago my old combo started leaking and left six 10p size drips on a drive - customer demanded that all the drive should be cleaned approx 450 square meters of the stuff - er, no chance - I cleaned the blocks that had oil and you couldn't see where it had been and as it was single blocks didn't look out of place - needless to say he cancelled after the next clean.
I've now done around 6 large oil spills where the garage has failed to do the sump bolt up properly they always pay for a complete drive clean at cost ++
However these are larger spills like 4 to 5 litres worth of oil
