Plastic Spiky Dryer Balls

⚠️ USE WITH CAUTION

Reducing drying time and static in the dryer

Materials

PVC or ABS hard plastic

Common claims

Reusable
Reduces drying time
No chemicals

Concerns / watch-outs

Hard plastic dryer balls can off-gas low levels of plastic compounds at dryer temperatures
Abrasion from tumbling can release microplastic particles that embed in fabrics

Notes

While better than dryer sheets for chemical load, plastic dryer balls have their own concerns at heat. Wool dryer balls are the preferred reusable alternative.

Cleaner alternatives

wool dryer balls

Sport / Activewear Laundry Detergent

⚠️ USE WITH CAUTION

Washing athletic wear and performance fabrics

Materials

Enzyme-enhanced surfactants
Odor neutralizers
Fragrance (often light)

Common claims

Removes sweat and odor
Safe for performance fabrics
Enzyme-powered

Concerns / watch-outs

Many sport detergents still include fragrance and optical brighteners that can damage performance fabrics over time
Synthetic odor neutralizers add chemical load without providing safer odor control than enzymes alone

Notes

The enzyme-forward versions work well for activewear; choose fragrance-free varieties and skip optical brighteners that degrade moisture-wicking coatings on technical fabrics.
