Vaska + Purex Crystals = great softness
After trying to get our towels soft I (with the help of the forum) stumbled on Purex Crystals. So I picked up some of the Fresh Spring Waters scent...
Using Vaska free for the wash and the crystals in the tub the towels are pretty soft. And using this combination gives great softness in regular clothes as well.
Not sure I'm in love with the scent - it smells "weird" to me being that we're used to Downy. But I'm going to give it a shot and see if we grow to like it. Or maybe try the other scents.
But the softness from the combo seems to be very good to me.
