Debate over dryer balls: some say they don’t work


Some dryer balls are spiky.

Dryer balls are baseball-sized balls that are typically made of rubber, plastic or fabric. The promotional material for them says when you put several in a clothes dryer they’ll hasten drying; they’ll also soften clothes and reduce static, serving as a substitute for chemical-based fabric sofeners.

I didn’t know that dryer balls existed until I encountered supportive mentions on the David Suzuki Foundation and B.C. Hydro websites.

The theory behind using the balls is that they help to prevent laundry from clumping in the dryer. In doing so, the laundry dries more efficiently. The balls also retain heat and boost the drying process by passing along their warmth. After reading the instructions and promotional material for several brands of dryer balls, I am unclear about how they soften clothes and reduce static.

Several people have tested the dryer ball claims and have concluded that they generally do not reduce drying time.

A Grade 8 student in North Carolina, David Wicklin, conducted an experiment with dryer balls for a national science poster competition and won second place in his category. He did 20 loads of family laundry with dryer balls and another 20 without, and found that there wasn’t much difference in drying time. He worked out a way to make comparisons fair with the help of a scale.

The website also found that dryer balls make no difference to drying time.

The writer at Green Energy Efficient Homes went looking for evidence to back claims that dryer balls can reduce drying time by up to 25 per cent, and concluded that the balls are a gimmick.

Popular Mechanics checked the fabric softening claim and declared: “Difficult to detect a noticeable difference — other than increased noise — when dryng with the balls.”

On the other hand, the maker of this YouTube video is convinced that the balls reduce drying time. As for banishing static, she offers an unequivocal it doesn’t work.

And many of the commenters on for Woolzies Dryer Balls insist they work. Sample headings: “Makes a Big Difference in Drying Time” and “they work great, remove static.”

Why do dryer balls appear to work for some people and not for so many others? After wading through all those articles, here’s my guess. It depends on what’s being dried. Laundry is not a set thing. Some people have a lot of natural fabrics, others lean to polyester. Some loads have a lot of small things, like socks and underpants which can spin about freely. Others have bedsheets and blankets that are prone to clumping, and might benefit from the pounding of dryer balls to loosen them up.

This would be a good topic for one of my favourite TV shows, Mythbusters. But the visuals might be lacking. Not a lot of TV excitement in having balls tumble about in a dryer.
