Eddie, I use Persil Univeral powder for towels because of its anti-foaming properties in the first spin. The finished, well rinsed loads have no smell, fragrance or odor. I mix it with an equal amount of Tide HE powder along with the STPP and Oxygen bleach for undershirts because I double the detergent dose and the Persil kills all suds at 190F.
I really hold the power companies to blame for all of this cold washing shit. Here we have these expensive HE washers dominating the market that use small amounts of water in the first place and the power companies are still telling people to wash in cold water. Most of it is simple economics on the part of the power companies because by reducing the load, they do not have to invest in new generating facilities, hence more profits for the companies and their shareholders, the selfish bastards. I don't know how often the washing machines have to be cleaned with those special products to get the gunk out that is left behind by poor washing practices, but it would seem that the extra cost of buying this product could pay for the energy to wash a few loads in the few gallons of hot or warm water that just might obviate the need for the special washer cleaners, but the people who wash in cold water, especially in the winter, don't think of that or just don't think, period. Sheeple
