you say its part of the tools of the trade yet you said you don't need it, just clean the material you said,
no wonder the customer can still smell it if thats all you do, maybe you should of said, clean the material like leather but then use an o3 machine to get rid of any deep penatrating odours, would that not of been a better answer roger.
also if its part of the tools of the trade, and you say that smoke can not be rid of without physical force then why is it part of the tools of the trade?
