A: To preserve the exceptional quality and elegance of CASTELLO 1935 luxury linens, it is recommended to wash them in cold or lukewarm water using a gentle cycle and mild detergent, avoiding bleach or harsh chemicals that can damage the fibers. Linen fabrics benefit from being dried naturally, either flat or on a line, to prevent shrinkage and preserve their texture, though low-temperature tumble drying is acceptable if necessary. Ironing is best done while the linens are slightly damp to achieve a smooth finish and maintain their natural luster. Following these care instructions will ensure your linens retain their durability, softness, and timeless Italian craftsmanship for years to come.
