🧠 A Few Notes on “Film” and Microbiome Concerns

• Many conventional pods (including some Cascade formulations) use polyvinyl alcohol (PVA) film that’s designed to dissolve in the wash, but questions have been raised about incomplete breakdown or environmental persistence, and some people report visible residue on dishes. (UFine)
• The concern with gut microbiome effects mainly comes from the idea that very small amounts of detergent chemicals could remain on dishware and be ingested with food; this is why fragrance-free, plant-based or enzyme-only detergents are often preferred by people aiming to minimize exposure.

💡 Tip: Using hot water cycles and making sure your rinse aid is working well (or switching to a natural rinse aid) can also help reduce film and residue on dishes, no matter which detergent you choose.
