Plenty of web pages give advice about caring for silk, dry cleaning, and laundering silk yourself. Instead of repeating all that good advice here, I’m going to warn you about some of the things you don’t want to do with silk.
With a little care, your silk can last a very long time. Here are some things to avoid. Don’t spray your silk with perfume, deodorant, or hair treatments. Never bleach silk. Don’t store your silk where it is exposed to sunlight for long periods of time. Minimize exposure to water and don’t wring silks dry. Never torture your silks in the dryer.
