All of the indoor surfaces have been coated with the complex emissions from the cigarettes, not just the carpets. What she needs to do is give the house a 'Modern Spring Cleaning' on all painted/varnished and other hard surfaces as well, using TSP (Tri-Sodium Phosphate) in water (a cup per gallon), rinse and dry rapidly. The SVOC (Semi-Volatile Organic Compounds) that are oil-like are holding a fine dust in them and this coating is truly odourous. It will also come to the top of most repainting unless removed first.

The carpet cleaning should be done using a quality, but un-scented, surfactant. Many of the better, unscented dishwashing detergents work very well indeed. This removes the SVOC coating from the fibres, taking the odor with it.

From: "ryan sherry" ryanshrry@... Date: Fri May 12, 2006 7:24am(PDT) Subject: removing cigettte odor from houseI have a client with rental unit that had a former heavy smoker. All clothing has been removed from house, with carpets cleaned and a general cleaning - but odor perisists. She want's to aggressively, but safely remove odor for next tentant. My guess is that odor probably still remains in carpet - and possible fiberglass liners in ducts and AHU. Is ozone or other concoction at high levels an option - if proper measures are used to remove whatever is applied. I am always nervous to apply dangerous chemicals into houses, but if can be done safely and is affective, I may recommend it. Any insight would be greatly appreciated. Thanks in advance.
