Removing melted pitch
I have a small flat roof over my porch covered in pitch.
In the July heatwave (and during the current hot spell) some of the pitch has melted and fallen onto my front path where it has quickly solidified.
I managed to remove some using a scraper but most is stuck fast to the paving stones.
Is there any way I can remove this eg a solvent which will dissolve this residue and which I can then easily wash away with, say, water?

You can use heat to soften it so you can crape and remove as much as possible. Then, almost any paint solvent (paint thinner, mineral spirits, lacquer thinner...) should work. Lacquer thinner will evaporate away quickly so I'd use paint thinner or mineral spirits to begin with. Then if you still have a stain from the solvent a few days later you can use lacquer thinner or alcohol to remove the mineral spirits. Be careful that you don't things worse. The solvent can carry it deeper into the pores making it almost impossible to remove.
