Cold Water Washing
For laundry will become more common as more technology/chemicals make their way down from TOL commercial and residential laundry detergents.
Even before Tide "Cold water", regular Tide was highly rated for cleaning in cold water. With the advent of bleaching activators such as TAED being accepted by the EPA and other bodies as an approved disenfectant, the need for hot water (temps above say 120F)will decrease. This also fits into the push for energy conservation, as no matter how the water is heated, it still requires energy.
Never thought I'd so much washing in cool,war, or cold water, but the European commercial detergent was given, does a wonderful job. Bonous is that my ironing day is considerably easier with less wrinkles to deal with.
Our local hand laundry tells me that I'd be surprised how much laundry commercial laundries do in cold water. Table linens especially as again, it makes for less ironing. One advantage have noticed when doing dress shirts, as long as the detergent has good system for keeping dyes from transfering during the wash/locking colours, can wash all sorts of colours together. Items that are likely to bleed or known to are laundered in a different load obviously, but so far everything comes out well.
