A:Answer Hello, thanks for reaching out to us! The right setting depends on what types of fabric you are drying For cottons and most linens, we recommend using the Cotton setting. For wrinkle-free, permanent press, delicate items, and knits we recommend using the Casual setting. We hope this information helps, and if you have any questions in the future, please let us know. We are here to help!- Kianna@GEA
