About two  weeks after unit had arrived, it started emitting a smell that resembled stinking shoes.  I have placed the unit outside on a covered deck all day for at least 3 times.  The unit still gasses off the smell, maybe a little less.  I have wiped it down with vinegar, did not seem to help.  Do you have any other suggestions I could try?

If the smell stops, I would otherwise be happy with it.
