Are natural fiber dish brushes a real upgrade?
Based on 1 peer-reviewed studykitchen
Verdict: Safer
Yes. Tampico or horsehair brushes don't shed microplastics and hold up to daily dish washing.
What's actually in it
Natural fiber dish brushes use tampico, agave, or horsehair bristles in a wooden handle. They hold up to hot soapy water and scrubbing without shedding plastic. The only plastic-free maintenance: dry between uses.
What the research says
A 2025 study in Sci Adv tracked microplastics from gut into blood and brain in mice. Every plastic source cut helps.
Pick a quality natural fiber brush with a replaceable head. Replace the head annually (cheaper than a whole new brush) and compost the old head.
