Dryer sheets fulfill two purposes.
1. They stop static cling.
2. They perfume your clothes.
The first purpose is useful. The second, not so much. We take it for granted that every product we use gives off a scent, but do you honestly need your clothes perfumed over and above the scent they get from detergent and fabric softener (if you use it)? And that comes in addition to your deodorant, soap, shampoo, conditioner, body lotion, hand cream and so on…
When you smell perfume on your clothes a week after you washed them, it is because the chemical that gives off that scent is still in the fibers. Dryer sheets are one source of chemicals that is easily avoided.
A year and a half ago, I bought dryer balls. They somehow, magically, stop static cling. Can’t quite figure how they do it, but they do – and they don’t add any chemicals to my clothes while doing so. The balls are inert. They are now exactly as they were when I bought them, so I imagine they’ll last for many years, which will save me money. One less product to buy.
These are the particular ones I use. My guess is that other brands work just as well.
