I’ve been using dryer sheets to soften my clothes and reduce static for years. Dryer balls, which are balls made from plastic or wool, are marketed as a more effective and chemical free alternative to dryer sheets.

The question is, do dryer balls actually work?

Makers of dryer balls claim that placing them in your dryer during cycles will reduce drying time, eliminate static cling (when clothes stick to each other or to your body due to static electricity), and soften clothes.

Instead of blindly trusting these claims, I purchased this pair of dryer balls and put them to the test. My goal was simple, determine if these claims are actually true by drying clothes with and without dryer balls then measuring the difference in drying time, static cling, and softness.

Based on the results of my tests, it’s clear that dryer balls effectively reduce drying time (by 13%) and wrinkles, but they don’t have any measurable impact, positive or negative, on static cling or softness.

Putting Dryer Balls to the Test: Do They Really Work?

Over the course of eight weeks, I ran ten loads of laundry, five without dryer balls (the control group) and five with two dryer balls (the experimental group).

For this experiment, I used Whitmor plastic dryer balls which are very affordable and get excellent reviews on Amazon, but there are dozens of other options available and some people swear by wool dryer balls like these ones. More on the difference between plastic and wool dryer balls later (skip right to it).

Drying time, static cling, and softness vary based on washer settings, the make/model of the dryer, the dryer settings, the size of the load, and the types of clothes in the load.

To control for all these variables, I ran each load through the same wash settings, I used the same dryer with the same settings, I cleaned out the lint filter before each load, and I ran each load with the exact same clothes (5 cotton t-shirts, 2 hooded sweatshirts, 2 pairs of sweatpants, 5 pairs of socks, and 4 pairs of mesh gym shorts). I did not put dryer sheets in any of the loads. I alternated loads with dryer balls and loads without.

Do Dryer Balls Reduce the Time it Takes Clothes To Dry?

To measure the impact dryer balls have on drying time, I set my dryer to automatic-dry mode so it buzzed as soon as each load finished drying completely. I used my stopwatch and sat in the next room to measure drying time down to the second.

Much to my delight, all five loads that ran with dryer balls dried in less time than the loads without dryer balls.

Based on the results of my experiment, the claim that dryer balls reduce drying time is absolutely true.

Loads without dryer balls took an average of 47 minutes and 37 seconds to dry compared to the loads with dryer balls which an average of 41 minutes and 20 seconds to dry, a 13% reduction in drying time. Here are the full results:

Drying Time: Loads Without Dryer Balls (Control Group)

  • Load 1: 47 minutes and 38 seconds
  • Load 2: 48 minutes and 12 seconds
  • Load 3: 46 minutes and 52 seconds
  • Load 4: 47 minutes and 20 seconds
  • Load 5: 48 minutes and 6 seconds

Drying Time: Loads With Two Dryer Balls (Experiment Group)

  • Load 1: 40 minutes and 23 seconds
  • Load 2: 43 minutes and 7 seconds
  • Load 3: 42 minutes and 41 seconds
  • Load 4: 39 minutes and 2 seconds
  • Load 5: 41  minutes and 29 seconds

Saving a few minutes may not seem significant, but in the long run, even a few minutes can save you hundreds of dollars in energy and gas.

Based on everything I learned during my research of dryer balls, the more you use, the faster your load will dry. Some people recommend using up to six dryer balls in each load.

Do Dryer Balls Eliminate Static Cling?

What about the claim that dryer balls eliminate static?

The short answer is, no.

The long answer is that static cling is a very difficult characteristic to measure, however, the loads with dryer balls showed directionally that dryer balls might help reduce static cling.

To measure static cling during this test, I quickly opened the dryer door after each load finished and carefully examined every item and noted the number of times static cling was present.

Regarding the claim that dryer balls eliminate static cling, the results were inconclusive.

The loads without dryer balls averaged 4 instances of static cling per load. The loads with dryer balls averaged 3 instances of static cling.

Directionally, dryer balls showed improvement, but I need a larger sample of data to definitively declare this claim true or false.  Below are the full results of each load.

Static Cling Instances: Loads Without Dryer Balls (Control Group)

  • Load 1: 4
  • Load 2: 3
  • Load 3: 5
  • Load 4: 4
  • Load 5: 4

Static Cling: Loads With Two Dryer Balls (Experiment Group)

  • Load 1: 5
  • Load 2: 2
  • Load 3: 2
  • Load 4: 3
  • Load 5: 3

The loads with dryer balls showed a reduction in static cling, however,  the sample of data was so small that a couple more/fewer instances would drastically change the results. Due to this, I can not say with confidence that dryer balls actually eliminate static cling.

Do Dryer Balls Improve the Softness of Clothes?

Measuring the impact of dryer balls on the softness of clothing, similar to static cling, is extremely subjective. There is really no scientific way to measure softness. The only way to get any sort of measurement is to touch the material and assign a Softness Score based on my personal opinion. So that is exactly what I did.

To measure whether dryer balls improved the softness of clothes, I carefully examined each load within 10 minutes of drying. I rated the overall softness of each load from 1 (not soft at all) to 10 (the softest load of laundry ever).

The results, similar to static cling, were inconclusive.

The average Softness Score for both the loads with and without dyer balls came in at exactly the same average of 7.4. As I mentioned, measuring softness a highly subjective process. Based on my judgments, I couldn’t feel any meaningful differences between loads with and without dryer balls. Here are the full results:

Softness Score: Loads Without Dryer Balls (Control Group)

  • Load 1: 7
  • Load 2: 7
  • Load 3: 8
  • Load 4: 7
  • Load 5: 8

Softness Score: Loads With Two Dryer Balls (Experiment Group)

  • Load 1: 7
  • Load 2: 6
  • Load 3: 8
  • Load 4: 8
  • Load 5: 8

Unexpected Benefit of Dryer Balls: Fewer Wrinkles

During my experiment, I noticed fewer wrinkles in the clothing that was dried with dryer balls.

I wasn’t expecting to see this because reducing wrinkles isn’t a widely recognized benefit of dryer balls. I noticed the biggest difference between my cotton T-shirts.

Check out the side-by-side comparison of the same shirts dried without dryer balls (left) versus with dryer balls (right).

How Do Dryer Balls Work?

The science behind dryer balls is simple.

During dry cycles, dryer balls create separation between layers of clothing which allows hot air to circulate more easily and dry the load faster.

Without dryer balls, wet clothing sticks together for the first several minutes of the dry cycle until it becomes dry enough to separate on its own.

As they bounce around, dryer balls gently agitate the fibers of the clothing which contributes to the softening of the fabric (allegedly) and, based on my experiment, helps reduce wrinkles.

Although I didn’t see a significant difference from my tests, dryer balls are known to minimize static cling. They do this by maintaining separation between items of clothing, reducing overall friction, and preventing the imbalance of electrons that causes static cling. 

Also, as I mentioned in a recent post comparing dryer balls and dryer sheets, wool dryer balls absorb and hold onto moisture during the cycle. That moisture helps elevate humidity which limits the chances of static. To enhance this effect, spray wool dryer balls with water before starting the cycle. Since wool is denser than most materials, it will hold onto that moisture and keep humidity levels higher while everything else dries completely.

Plastic vs. Wool Dryer Balls

There are two types of dryer balls on the market, plastic with spikes or wool. I used the plastic ones for my experiment but some people swear by the wool ones.  Here are the pros and cons of each.

Plastic dryer balls are hypoallergenic, non-toxic, and safe for all types of clothing materials. Their small spikes get into the folds of clothing allowing them to create separation and improve air circulation which speeds up drying time.

There are several very affordable plastic dryer balls to choose from on Amazon with hundreds of reviews to browse. I highly recommend this four pack from Whitmor which have over a thousand, mostly 5-star, reviews.

Wool dryer balls are all-natural and contain no chemicals. Although they don’t have spikes like plastic dryer balls, they are just as effective.

Wool dryer balls are heavy, yet soft and don’t make as much noise as the plastic kind. They absorb moisture which aids in drying but they also release moisture which reduces wrinkles and static.

One of the best advantages of wool dryer balls is that you can add a few drops of essential oil, like this lavender one, on the dryer balls to infuse a wonderful scent to your clothes.

Like plastic dryer balls, wool balls are also very affordable and there are several options available on Amazon. The highest rated by far is this six-pack from Smart Sheep which has over 15 thousand mostly 5-star reviews on Amazon.  

Bottom Line: Do Dryer Balls Work?

Based on the results of my experiment, it is pretty clear that dryer balls do, in fact, reduce drying time. However, dryer balls did not make a significant difference in static cling or softness.

The impact of dryer balls will vary based on what type of clothes you are drying, what type of dryer you have, how many balls you use, and the type of balls.

Fortunately, they are inexpensive, require no effort to use, and there is a huge selection to choose from on Amazon, so why not give them a try?

  1. We’ve been using wool dryer balls for about 2 weeks now. I have made them all. We have had zero static on any of our clothes…

  2. 2 dryer balls, in a loaded dryer, isn’t a valid trial, & led you to incorrectly report a below par performane.

    most users who’s comments i’ve read, advise using 4-6 balls, MINIMUM.

    your dryer ball review, is hardly a ‘prudent review’, and as silly as one for an automobile, with a 5 speed transmission, which you test-drive using only 1st & 2nd gear.

    • Hi D.C.

      Thanks for the feedback.

      Most manufacturers recommend using 2 to 4 balls, depending on the size of the load. The loads I tested were relatively small and didn’t include any really heavy items like jeans or towels.

      To your point though, the general consensus from users is the more dryer balls you use, the more effective they’ll be. I made a brief note of that at the end of the article, but I’ll update it to make it more clear.

      Next time, I’ll test 4 to 6 dryer balls and compare the results.

      Thanks again! We always appreciate feedback like this.

      Andrew
