Good idea! I removed and washed all ashtrays, and packed away all lightrs etc. from sight the night before quitting. I also checked all my bags, drawers and secret stash places for any remaining packs... Emptied all bins and took trash out. I then avoided my usual smoking pit stops...
A week later I bought one of those small floor steamers and steam cleaned the walls, floors, cupboard doors, mirrors, light fixtures etc. etc. and washed all the curtains. I washed or dry cleaned all my coats and stuff like that, and thoroughly aired everything.
Now all one can smell in my house is cookies or strawberries or other yummy, yummy things lol.
