Thank-you @Sarah977 for your reply, you're always so very helpful! I'm learning a lot. In reviewing my Ring video footage, I also noticed my guest smoked a pipe, (no attempt to conceal the fact that he was smoking as he walked inside), as well. So I have an interesting mix of stale tobacco and fruity (?) smells filling the air. I've always been a fanatic about drying my bedding in the sunshine,--and managed yesterday to steam clean some area rugs, (thankfully the main flooring is tile), and set outside to dry in the sun as well as some washed bedding. (I'm missing the sun today as we have had storms and quite a bit of rain here in San Antonio.)
Anything that I have not been able to wash, (i.e. lampshades), still smells, in spite of spraying with "OdoBan". I'm not entirely sure if the bedding is odor-free or not,--I seem to have the smell stuck in my nose at the moment. (I am using your tip, and after washing everything twice, I am doing a vinegar rinse.)
I'm also running 2 air cleaners. The area smells better, however, if I were renting a smoke-free place, I would turn around and leave,--so obviously I have a lot of cleaning left to do. I plan on tackling the walls next. I've read that wiping them down with a 20/80 ratio of vinegar/water may help. Thank-you again, @Sarah977 for your help; have a wonderful day!
