What you'll do:
Make a ball of aluminum foil about the size of a tennis ball. It doesn't have to be a super compacted ball; just ball it up like you were throwing it away. All you do is throw it in your dryer on top of your wet clothes. It comes out looking like the picture below. This works like a charm! I first tried it with a load full of towels. NO static at all!! And the clothes were still soft.
This is not a fire hazard as some people may wonder. Foil is not a combustible material. Also the heat used in dryers in the indirect type of heat. No dangers. It is no more dangerous than putting zippers or metal buttons in the dryer.
You may wonder why it works. I wondered that myself. Sheryl at The Cents'able Shoppin figured it out and her blog post made sense to me. The foil itself actually becomes a conductor to attract the static. Clothes come out static free.
Sheryl also points out that dryer sheets put a film on clothes which makes them less absorbent. This film is not good for your clothing; making it wear out faster. That same film is made out of chemicals (a laundry (pardon the pun) list of them) which are not good for you. Those chemicals stay on your clothes and can and do rub off on your skin. More about those dangers here. FYI that site talks about using wool balls instead which works on the same principal.
Aluminum dryer balls can be reused over and over for about 6 months. Some say you can use them indefinitely. This makes loads (sorry...for being punny) of sense!
Whatever method you choose for an alternative to dryer sheets, enjoy the added boost to your income.
