Avoid liquid chlorine bleach (LCB), fabric softener, dryer sheets, and washer or dryer balls. Harsh detergents can do damage to fine linens and particularly high quality sheets. LCB can weaken the rayon fibers, reducing the life of your sheets. Fabric softener and dryer sheets can leave a film on the fabric, reducing the moisture wicking properties. Dryer sheets can cause discoloration, and washer and dryer balls, similar to washing with towels, can cause pilling.
