Well "heck"- I forgot about that. I have an enclosed back porch with floor to ceiling windows
on three sides. I have tried febreeze, baking soda, vinegar, this stuff in a bottle with a wick that they use in the hospital, even opened the windows (high temp 20F), room freshener and scented candles. I'll try the coffee tomorrow. It works for a few hours and then the smell is back. It's like an evil entity!!
