Can you put dryer balls in the washer?

Wool dryer balls have become a popular eco-friendly alternative to dryer sheets. They soften fabrics and reduce drying time when used in the dryer. But can they also be tossed in the washing machine for added benefits?

Wool dryer balls should be used in the tumble dryer. The wool is durable enough to withstand the heat and tumbling action. However, the washing machine environment can be too harsh for these balls.

The agitation and spinning can cause wool dryer balls to pill, shred, and fall apart quickly. Chunks of wool can then end up stuck to clothing, possibly causing damage.

Using wool dryer balls in the washer also reduces their effectiveness in the dryer. For best results, reserve wool dryer balls for the dryer only.

When should you put wool dryer balls in the washer?

Even though we don’t recommend it as a regular practice, it’s a good idea to clean wool dryer balls every few months by gently washing them. Place each ball in the bottom of a clean sock and wash them in hot water on a gentle cycle.

Risks of putting dryer balls in the washing machine

While it may seem harmless, placing dryer balls in the washing machine can cause several problems:

Clothing damage

Wool dryer balls can pill, shred, and discolor clothing. The agitation tears at the wool fibers, causing pilling and holes, especially in wool garments. Dyes may also bleed onto lighter colors.
Even plastic balls can damage delicate fabrics if caught or wedged into the material. The hard plastic can snag and pull threads.

Clogged machines

Lint and fibers released from wool dryer balls can accumulate inside pumps and drainage pipes. This builds up over time, clogging the system.
Plastic balls may wedge into small openings, jamming the mechanics. Clogs can lead to costly repairs.

Reduced lifespan

The harsh chemicals from laundry detergent will cause accelerated wear on dryer balls.

The best way of using wool dryer balls

Wool dryer balls provide multiple benefits when used properly—in the DRYER:

Soften fabrics naturally. Tumbling action separates fibers rather than coating fabrics with harmful chemicals. Drying towels, sheets, and clothes with wool dryer balls will make them feel gentle without artificial softeners.
Reduce drying time. Balls circulate air and distribute heat more efficiently allowing moisture to evaporate faster. Clothes dry quicker, saving time, and energy usage.
Reduce static cling. Friction between the balls and clothes releases static charge built up in fabrics. Prevents clothes from clinging together and stretching out.
Reduce wrinkles. Separating and aerating clothes as they tumble minimizes wrinkling. Results in less ironing.
Freshen laundry. The friction helps release odors trapped in fabrics for fresher-smelling clothes. A natural clean without perfumes.
Hypoallergenic. Contains no dyes, bleach, fillers, or other chemicals that can cause skin irritation and allergic reactions. Safe for those with sensitivities.
Eco-friendly. Reusable for hundreds of laundry loads. Biodegradable and non-toxic materials avoid plastic waste.

Follow these simple tips to properly use wool dryer balls and unlock their full effectiveness and convenience. Do not use them in the washing machine. By reserving balls for the clothes dryer only, they will soften fabrics naturally for hundreds of eco-friendly loads.

Although they come unscented, you can add 3-4 drops of your favorite essential oils to them. You can also buy Smart Sheep scenting spray to make your soft clothes smell like orange, lemon, or lavender.
