The full answer
Not always required, but often genuinely helpful
Well-cleaned, non-porous cookware (like stainless steel or glass) can generally be shared safely after thorough washing. The bigger concern is scratched non-stick surfaces or porous materials like wood, which can trap gluten particles even after washing.
A practical approach
Many households choose to dedicate a few specific items — like a cutting board and a colander (both hard to fully clean) — to gluten-free use only, while sharing well-cleaned pots and pans without issue.
Important context
Individual symptoms, reactions, medical histories, food products, and local labeling rules can vary. Community experiences are not medical evidence.
