A few months ago I was reaching for a bottle of Shout from the shelf above the washing machine and I lost my grip. It fell directly on the knob that I turn to switch from cold to hot water. I wasn't too upset since our washer is OLD (we bought a refurbished one 13 years ago and it's still kicking) and I tend to wash a lot in cold anyway.
But now I'm wondering...can you wash diapers in cold water? I've got the girls' stash that I plan to use for this baby as well but it just hit me the other day that I can't switch to hot water with the broken knob.
