I have spent over 30 years in the bridal industry, in the theatre, & purchasing silk yardage by the bolt from Thailand....and will say from all this experience, that silk a natural product...so it should be treated naturally.    It is so simple... >>What would you wash your hair with? 

• A regular liquid soap meant for lingerie?   NO !
• A hand soap (a complexion bar)?   NO !
• A special liquid soap bought at a high-end department store...especially for fine lingerie?  NO again! 

Think of silk as you think of your hair.  Because silk GROWS from an 'organic' body.  Hopefully, you shampoo your hair with a very high-quality shampoo; one recommended by your hair-sylist.  THIS is what silk should be washed with.  And always...air dry it indoors without the sun directly on it. 

I prefer NOT to dry-clean, because this process will remove the natural oils from the natural threads.   There's a "Part 12" link for the entire history of silk that should be read by anyone embarking on the cleaning of silk.  Most of it supports what I am saying here.

Even a preferred lingerie liquid soap would be better in my mind than dry-cleaning.   That said, using a fine shampoo with a conditioning follow-up BY A HIGH-END MANUFACTURER, will produce the refreshing and lustre you want RETURNED to your silk fabric.
