Towels and the Sanitary Cycle
There has been a discussion recently about whether hot washes contribute to scratchy towels. I promised to post my results so here it goes.
Washer: German Whirlpool Duet
Load: about 22 lbs. of towels
Cycle: Bulky Items at 203F with one extra rinse and 1200 rpm spin
Water: well-water at 21 grains per gallon
Detergent: powder for whites
Dosage: 150 ml (about half a cup) according to manufacturer's recommendation
Softener: Downy Simple Pleasures, cap filled to line three
Drying cycle: Cupboard Dry (normal dry) at regular temp
Now, the outcome. Well, I do have to say that the towels felt a little rougher that the one towels I did not include in the wash. I am not totally sure, however, if that comes from the hot water, the hot dryer or the high water hardness. (?) I did notice all clothes coming out softer once I upped the detergent dosage to what the manufacturer recommends for hard water. I also have to add that I have a Bosch condenser dryer, which gets very hot in the process - I think it peaks at 158F. That being said, my towels emerged super clean from this wash - even slightly better than at 140F.
So, the result isn't all too clear, I fear. I think I'll have to do some more experimenting and get my two unused towels out, boil-wash one and compare. But at least I can say that, yes, somewhere in the process, heat made my towels rougher. Oh, and the towels say to wash at 140F on the tag.
Here's the full load and a link to the nice water level I get on Bulky.
