Notre Dame laser cleaning options for fire damaged limestone. Lasers vs Fire video - Restoration.

Unfortunately, Notre Dame is not just covered with a surface coat of soot. The demo would have been more impressive if the limestone had been seen to be glowing white hot. That would have taken about half an hour with that blowtorch turned to maximum and playing on the one spot.
