Is it safe to use a plastic dish brush with hot water?
Based on 1 peer-reviewed studykitchen
Verdict: Use Caution
Not ideal. Hot water and abrasion shed microplastics from the brush into the dishwater.
What's actually in it
Plastic dish brushes are polypropylene or nylon bristles in a plastic handle. Hot water + scrubbing pressure + friction sheds bristles over time. The particles stay in the dishwater and can land on rinsed dishes.
What the research says
A 2025 study in J Agric Food Chem documented plastic particle release under heat and friction.
Switch to a wooden dish brush with plant-based bristles (tampico, agave, or horsehair). Last for years and compost when done.
