Purchased Ultra Downy (197 load) at Costco. Product is very thick had to add water to product to get it to pour out of dispensing cup. We have continued to use product adding water to dispensing cup as well as container to help thin product. Recently both my wife and I are feeling itchy spots on upper back. we have discontinued use of this container. Why is this particular containers product thick? What would cause this issue? Any help is appreciated
