Hello folks: Here is an odd question. Here at my shop we are trying to help a local luthier get his guitar making business up and running. He does good work and the guitars are nice. Here's the problem.....The guy is a heavy smoker and his guitars stink....literally! We can't open the cases and display the guitars because they reek so badly. Is there anything we can do to de-funk-ify these instruments? Thanks in advance for any help!
