How to clean smoke damage
Get permission from a fire marshal to safely re-enter your home.
Do not enter a house or other building affected by fire until you have received word from a professional that it is safe to do so. How soon after a fire you are allowed back in the building will depend on the severity of the fire and the measures employed to put the fire out.
Assess the damage to your belongings once you are back inside. Decide what you want to try to clean, and what you need to discard.
