I wish they wouldn't use so much chemical scents, the only thing I use here in the barn is Pine-sol, small bit mixed in water to cut odours in the horses stalls, also to dampen the alleyway of dust when I sweep.Yes, I’m sensitive too. There may not be a scent but there are other ingredients that coat the clothes to lessen wrinkles. Venting up and above is best, so that air will move away and not be wafted back, depending on the wind direction.
