Soft water is wonderful - given half a chance I'd move back somewhere with soft water or get a softener (having mainly lived in hard water areas)
Clean kettles, clean washing machines, clean showerscreens, taps, shampoo lasts 4 times as long, scalp less flaky, skin less scaly - like some kind of lovely dream.
If you run a two 90 degree, empty washes a month, my machine had better be more efficient!
I was my towels at 90 with a good chug of vinegar, and that happens every couple of weeks after doing the soda treatment just once (when I first moved in), and making sure the water filter was cleaned out and my washer doesn't smell any more. Nothing will shift the black marks on the rubber seals though.
This is in a rented property's ancient washer/dryer and that really stinky and scummy when I moved in.
