Effective Detergent in Cold Water:
To manage that, you are going to need some pretty nasty chemicals to activate bleaches, enzymes and the like at temperatures below 80ºF (27ºC). Are they suggesting we "save the environment" with Cold water washes, but have to use Engine-Degreaser in our detergent to get good results (i.e. remove body oils)? Antibacterial Soaps?
That is ridiculous! Use the right temperature for the job, your machine will last longer, you will last longer and you will be cleaner, instead of relying on chemicals that end up creating super-dangerous bacteria. Like I've said: Once we switched from a Cold-Water only TL machine to the Miele, which heats its own water, I have not caught a cold to date (1 yr). My clothes are cleaner - not stiff or whiffy smelling straight out of the machine. The times the Miele has gone "Cold Water" on my (Automatic cycle), I can SMELL the difference!
As Launderess has put it, there are 3 (or four) components of laundry: Reducing any of them (Temperature, Time, Chemical and Mechanical action) requires increasing the others to compensate: Cold water washing = More detergent, More Washing time = More damage to clothes. Our Miele will increase the cycle time by about 30-40 minutes as you decrease the temperature from 140ºF (60ºC).
