No, this is not a reference to The Hitchhiker's Guide to the Galaxy. Much like the the simple washer savings baby step, I loved this idea because it only takes a second and it isn't something that I would have thought about on my own.
I live in a community where I can't line dry my clothes outside and I haven't reached the level where I am comfortable with wet clothes lying all over my house to dry. That means that I use my dryer and according to dryer tips there is an easy way to reduce the cost of each dryer load by 10%.
After throwing in all the wet clothes that have come out of the washing machine, take a big, fluffy, dry towel and throw it into the dryer with all the wet clothes. As this fluffy towel tumbles in the dryer with all the wet clothes, it helps to absorb the moisture in the wet clothes which allows them to dry more quickly. In the end, you get your clothes dry in less time and save a bit of money in the process.
I started doing this about a week ago and it seems to work just as claimed. it's one of the easiest 10% savings I have found in a long time.
