Yes, you can wash and dry 100% linen items. Linen is a durable natural fibre that becomes softer and more comfortable with each wash. To maintain your linen's quality, use cold water and a mild detergent to prevent shrinkage or damage. Avoid bleach or fabric softeners.

When machine drying, use low heat to prevent excessive wrinkling, or hang your linen garments to air dry for a smoother finish. However, for valuable or delicate linen items, consider a professional linen washing service to ensure they receive the gentle care they deserve. These services specialise in linen care, offering expert cleaning and ironing for a pristine, wrinkle-free result.
