Y'all could just take up smoking? Problem solved.
Thanks again for all of the comments. I used a couple of the more gentle cleaning ideas and that cut it down to a level that is tolerable. If I can find the ozone machine that might get rid of the remainder.
If you live close to Greenwood, private message me. I do not really want to loan mine out, but if you have a big plastic container that it fits in, you could come by and we could give it a try.
