I've managed to lighten some of the stains with Caustic soda but the heavier
one's are not budging.
These are oil stains that are ground in over some time, will burning them
with a parrifin torch burner eradicate them? dont want to go and buy
parrafin if it's not going to work.

Thanks

I know someone who used a torch on a paving slab. Aparently some paving
slabs don't do well at high temperatures, and it cracked sending bits off at
high speed. Don't know if it was an air pocket, or the centre expanding due
to the heat, with the outer staying cool.

Silly question this but...have you tried and tested this on ground in oil
stains on paving flags?

I doubt it the stain is from the carbon carried into the substrate by
the oil. Undiluted washing up liquid, with just a dash of water if it
to thick, worked in with a stiff brush and left for the rain to wash
away (eventually) works pretty well.

Have you tried a solvent like white spirit or petrol?
