my cousin was telling me she has cement on her drive from work carried out previously and was wondering the best way to remove it?
turbo nozzle and blast away at it ? i reckon this will leave some staining on drive also

Hydrochloric acid. Not your cheap weak rubbish from B&Q that sounds good 'cos it's eco. Load of crap.
Where abouts are you?

No it wont mark the surface but going at it with the turbo alone you will struggle and possibly damage the surface of each block and you'll be attacking one spot for many seconds if not minutes. The acid will soften and loosen.

Just give the area a good soaking before applying the acid.
Most 'brick' acids come in at anywhere between 10 and 30% concentrate and it is not unusual to dilute further. It can be a bit of trial and error to begin with. If you do mix then be sure to pour the acid into the water.
Full PPE essential as this is nasty stuff.

Not always necessary to just attack with strong acids. If there are polymers in the cement the acid will have little effect until the polymers have been broken down
