ive recently found some rayon shirts I really like, but how do you wash them without destroying them? everything I've read online says dry cleaning is the only way
For viscose most rayon a gentle cycle in a front loading washing machine is generally fine, though the more silk-like variants are less resilient. You might want to put it in a garment washing bag to make sure it doesn't get stretched while wet. If you don't have that it's dry-clean only.
Varieties like modal and Lyocell are machine washable.
