Is it OK to wash rayon and spandex in the washer on the handwash cycle?

Rayon should not be washed in a washing machine, even on a hand-wash setting. Spandex should also be hand-washed rather than putting it in the washer.

Rayon should be hand-washed in cold water using mild detergent. It can also be dry-cleaned. It should not be put in the dryer, but should be allowed to air dry. Rayon can be ironed while it is still slightly damp.

Spandex should also be hand-washed using mild detergent and lukewarm water. Washing it in a washing machine may cause it to lose its shape and flexibility. Spandex should not be wrung while washing, and should be rinsed with cool water. It should not be dried in a dryer, but should be laid flat to air dry.
