Another cleaning question

[starone]

My side driveway is tarmac and something has put mud marks all over it. It looks as if an animal with very muddy paws has trotted down it, but I suspect it is more likely to be the kids with their mopeds, putting them up on their stands and consequently making all these muddy marks (can't prove it). I have tried washing it down with plain water and scrubbing it with washing up liquid but it is still there annoying me. Any suggestions as to what I could use to get rid of it. Tarmac looks nice at first but it has little grooves in it that retain the mud.

Tried that pond50 and it is still there. Cleaned everything but the marks.

close the curtains, pretend it's not there.

Good idea BOO. Perhaps that's the answer.
