I keep a thick, clean bath towel in the clothes dryer at all times. It helps to quickly absorb moisture from a load of wet laundry. That means clothes dry much faster and that reduces my energy bills.
I read this hint on Mary’s column years ago and (of course) it works!! I actually did some comparison testing out of curiosity. That clean dry towel in the dryer shaves about 20 minutes per load from my drying time!
I do that too! It does save money.
