When are you starting the work Jon? It's just that John is down at the NCCA Carnvial today but I'm sure he'd be happy to talk you through the procedures etc that will be required. We've actually drawn up an instruction sheet on Fire Restoration. Basically for that kind of fire you'll need a high alkaline cleaner and cloths, preferably terry towels....lots of them. When you're wiping the walls, start from the bottom up. If you start from the top down and you get 'runs', these are virtually impossible to remove.
