Hi - subjued
The guys did not manage to move all the concrete snots ( blobs) off. So after the HCl I power washed with the Karcher and let it dry. Then I found somewhere a mention that B & Q brick cleaner has some HCL in it. So I bought 5 lts. This I diluted 1 to 1 ( The container says 1 to 2) and brushed in hard and left it 10 to 15 mins. Then out with the Karcher again.
Result is that the B & Q stuff has cleaned the dirt out of the tarmac and it now more or less blends in with the HCL treated areas. I have a slope down to the road and so the water and mess gets away well.
I am going to leave it all until next spring to see if the winter weather helps. I am quite pleased with my 'recovery action'.
Best of luck. Let us know how you go on.
Regards.
