Too expensive
I am not sure the product would have a great result when used in the average consumer's wash load. I'm sure they would still be washing in cold, too short of a wash time, no soak, entirely too much fabric softener or dryer sheets, etc. The product likely would not even have the chance to activate completely. Plus, it is the Coral Blast scent, which is horrible.
I always wash our towels in hot with Tide, Downy, STPP, and Ammonia. No issues with odor here. Washed a load of towels in my stepdads GE TL. Used the 2 hour soak option and towels cycle, of course hot water. Those towels smell 1000X better and actually feel very clean.
