Cotton is often washable and dryable, but Ariel advises checking the care label because cotton blends can require different treatment. The guide discusses lower washing temperatures for bright or dark items to help limit fading and dye transfer. It also directs readers to the garment label before tumble drying to avoid shrinking the item.

Ironing is another separate check. The reference recommends reading the specific instructions and describes working from the reverse while the cotton is slightly damp when appropriate. Do not turn a general statement about cotton into an unrestricted heat setting for every cotton-containing garment, particularly when other fibers or finishes are present.
