First, the felted wool dryer balls that I first posted about in January worked for nine months. Then the inevitable pills that formed on them started coming off on my clothes. What are all these little brown balls on my clothes? Pieces of the dryer balls. Can't have that! It's just making more work for me.
As for the tin foil balls, they didn't make it through a day.
First, they have tiny sharp edges all over them. No matter how much I tried smoothing them out, they had these sharp spots that I fear would damage fabric in the long run. It just can't be good to have all these tiny points scratching at your clothes wash after wash. I decided to try running the foil balls through with a big load of towels to see if that process would smooth out the edges. That led to the second problem. They were freakin' noisy! That surprised me. How much noise can tin foil make? As it turned out, enough to have me racing back to the dryer to stop the racket on that first try.
This whole process led me to researching the need for laundry softeners in general. The only reason I use softeners is to eliminate static cling. According to the information I read, static cling is caused by over drying. If I don't leave the clothes in the dryer too long, I don't have static cling. That's what I've been doing lately with great success. Off to remove those dryer ball pins from my boards.
