I decided to seach the net on dryer sheets and I found arguments for and against the use. All I can say is they worked for me. The net says they will get used to the smell and they will cease to work. Might be why they work for me since I only use them for the winter months.

I learned all I need to know about life by killing smart people and eating their brains.
