Wool dryer balls are the most popular—they’re hypoallergenic, absorbent, and quieter in your dryer than plastic or rubber balls. 100% wool dryer balls contain no chemicals, dyes, or fillers. Plastic and rubber balls may contain PVCs and other substances.
Some people store their dryer balls in the dryer and add wet clothes on top of them. Either can go in first since they will tumble around anyway.
Let the balls absorb the oil drops for at least 20 minutes. An hour or more is best for maximum absorption. [5] X Research source Only use oil-infused dryer balls in warm or no-heat cycles. Oil is flammable, and a high-heat cycle with overly-saturated dryer balls could be a fire hazard.
Wool balls absorb moisture from clothing in the dryer, maintaining a more humid environment, and helping you get rid of static cling and friction.
When wool dryer balls are new, they might leave some lint on your clothes. Use light-colored balls for light clothes and dark-colored balls for darks to fix the problem.
An auto-sense dryer will automatically stop once it senses that the load is dry.
Plastic dryer balls last even longer and may not ever have to be replaced unless they break.
Wool dryer balls are also compostable. Just toss them into an organics bin when they’re used up![13] X Research source
