where about are you
alkaline cleaning solution, and rags, to neutralise the smioke damage on the fabric of the building ie walls, ceilings, you are only cleaning it ready to re dec.
fogging will get rid of smells,
BUT you must remember ducting, floor voids, ceiling voids, smoke will have collected in all of those areas, all will need cleaning,
John Kelly is a very good source on this area aswell.
