How do you wash kilim?

Excuse me, I was wondering if you could offer some insight on the proper method for washing a kilim rug. I understand that these unique and often valuable pieces require special care, and I'm eager to learn the best practices to ensure that mine remains in pristine condition. Are there any specific cleaning agents or techniques that you recommend? Also, are there any common mistakes that should be avoided when undertaking this task? I would greatly appreciate any guidance you can provide.
