Sludge stains

[GQuigley67]

Remove from a driveway anyone? Tried fairy liquid and cleanser

 

[Last Plumber]

Jetwash ?

Tried scrubbing and stuff not budging it's a new driveway

Is this 'sludge' metal, as in heating system sludge ?
If it is you're gonna struggle.
Once it's in the stone it's in I'm afraid.

You could try acid brick cleaner but try an inconspicuous area first

It's a nightmare to get off. You could try vinegar first, you can get a gallon quite cheaply I'm sure, and then move up to brick cleaner as Last Plumber suggested.

Is it worth calling a specialist in? Some of the ideas given might actually make things worse?

Already made f all on this job, don't really want to spend a lot more. The original free standing boiler was a nightmare and weighed a ton, was impossible to get it out without some spillage

Sorry thought the £6.7k was profit hence making it worthwhile calling somebody in so you got paid.

Block paving?

Try some old fashioned washing powder , pile it up on the stain and just leave it ( assuming its not going to rain ) for a day/night .
Good luck
