Dear Connie -
Thanks for the link! It's funny that they say to run only hot loads when for eco-friendly reasons I run only cold loads. I think there's a way to make this work without cranking up the water temperature.
I am pretty sure other sites said to run a bleach no-clothes load to wash the inside of the washer, but we're out of bleach. So I've put that on the list!
We do leave the door open when it's not in use.
