How Long Do Wool Dryer Balls Last? How to Recharge Them

There are two major types of dryer balls, those made from wool and those made from plastic or rubber. Plastic or rubber Dryer Balls are formed from a hard material with many small nodules on the outside to massage the fabric and soften it as the dryer spins.

Dryer balls typically last for 1,000+ dryer cycles or 2-5 years. The exact life expectancy of dryer balls will depend largely on what material is used to make them and how many loads of laundry you do.

Dryer balls are an easy addition to your laundry routine that give numerous benefits such as reducing static cling, preventing wrinkles, decreasing drying time, and being hypoallergenic and eco-friendly. With all those details to cover, let’s get into the action.

Plastic dryer balls can also begin to dry out, but they are still a great option for people who are allergic to wool.

When to Replace Your Dryer Balls

You should replace plastic or rubber dryer balls when you begin to notice they are no longer as effective as when they were new. This is usually every three to five years.

Depending on how often you do laundry, wool dryer balls should be replaced every four-to-five years. 

A good indication for replacing your wool dryer balls is when they become larger, softer, and start to unravel. They will start to look pretty scruffy and pieces of the wool will tear off or the wool fibers will adhere to your clothes, making them look as if they are covered in pet hair.

How to Care for Your Dryer Balls

For the plastic or rubber dryer balls, you can leave them in the dryer until the next time you do laundry. 

If you use wool dryer balls, it is best to take them out of the machine and let them dry completely before the next laundry session. 

You might also want to think about washing just your Dryer Balls by themselves occasionally. This will remove any buildup of laundry soap on the surface and improve the performance of the Dryer Balls, regardless of whether they are made of wool, plastic, or rubber.

benefits of dryer balls

Adding dryer balls to your clothes dryer can give you several benefits that not even dryer sheets can’t give.

With all these benefits ou may be wondering if dryer sheets are necessary, we have a post that digs into that topic, check it out here.

The benefits of wool dryer balls are they reduce static cling, prevent wrinkles, decrease dry time, are hypoallergenic, and it’s more eco-friendly.

1. Reduce Static Cling

No one likes to have crazy static electricity in their laundry, dryer balls can help reduce static build-up.

Static cling can be reduced by drying a lot of different types of fabrics together. Cotton, wool, and synthetic materials all dried together helps decrease static.

Wool dryer balls are made out of wool, obviously, so they help prevent static cling by being a different type of material.

If you want to reduce your static cling even more, you can pin a safety pin to one of your dryer balls.

Metal is conductive so it will gather the static electricity and then discharge it into the dryer when it comes in contact with the wall of the dryer. Pretty cool huh?

2. Prevent Wrinkles

Wool dryer balls help prevent wrinkles by adding steam to your laundry. They do this by absorbing some of the water off your wet clothes during the drying cycle and then releasing it as they heat up.

This steam helps prevent wrinkles in the laundry. If you have a dry shirt that’s gotten wrinkly, you can spritz your dryer balls with water and then add the shirt to the dryer. Run a load with these damp dryer balls and the shirt will come out wrinkle-free.

3. Decrease Dry Time

Probably the biggest reason most people switch to wool dryer balls is that it can decrease drying time. They can reduce dry times by around 25%. That’s amazing!

Dryer balls do this by bouncing around in your dryer and creating pockets of air between the clothes. This creates better air circulation around the clothes which makes them dry faster.

This decrease in dry time means that your dryer will use less energy which means your energy bill will decrease. Decreasing your energy consumption and energy bill is something everyone loves.

If you want to further decrease your energy bill, you can air dry your clothes in the warmer months.

4. Hypoallergenic

People with sensitive skin, babies, or young children can sometimes form allergies to the harmful chemicals found in dryer sheets.

Wool is hypoallergenic because it doesn’t have any of these chemicals present and they have many of the same benefits as dryer sheets.

However, some people have a wool allergy, if you’re one of those people, don’t worry, you can use plastic dryer balls instead and still get some of the same benefits as wool dryer balls.

5. Eco-Friendly

Last but not least, dryer balls are more eco-friendly than single-use dryer sheets.

Dryer sheets are a single-use product and dryer balls can be used for several years with proper care.

Also, wool balls are made with natural materials which are eco-friendly and more sustainable than synthetic dryer balls which decreases their environmental impact.

But, you can add scents to your dryer balls by using your favorite essential oils. To do this, add a couple of drops of essential oils to each dryer ball.

There are a few types of essential oils that are known to be more of a skin irritant than others. They are citrus oils, cinnamon, clove, lemongrass, oregano, peppermint, and jasmine.
