I have had these rugs for a number of months now and really like them but I was literally taken aback when I cut the bags open.   The smell of ammonia was overwhelming and this was outside.  I rinsed them out and of course they have been rained on now but for a number of days the smell was very powerful.   We had three rugs and they all had this pungent, noxious odor.    I wouldn't say not to order them, just be aware that they will knock you over when you open the packaging.
