The machine to use is an ozone generator. They are available as air cleaners, but not recommended by some because ozone is also a pollutant. I bought one for my inlaws when they quit smoking, and it cleaned out the smoke stench in their house in 3 days. But for a smoker's house, you have to keep it running because the smoke continues to come out of fabrics for a long time. There are also the ozone cleaners that hotels use that will clean out the smoke in a room in 30 minutes (if someone smoked in a non-smoking room).
Look up air cleaners. There are 3 types: HEPA filters which require new filters frequently; electrostatic precipitators which have filters that can be washed in a dish washer (and produce some ozone); and ozone generators, which have plates that have to be cleaned periodically. For the ozone generators, you want to control the amount of ozone produced to be just enough to clean the smell, without smelling the ozone.
I hadn't heard anything about ozone harming the fabrics.
