Punki: I suspect Dryel doesn't have the same chemicals a regular dry cleaner would use, but you might want to avoid using it on your cashmere. I've always been told that dry cleaning chemicals break down the cashmere fibers (just like regular washing apparently does to rayon). It may come out fine the first several times, but eventually it will wear out much quicker than it should. Cashmere is just too darn expensive to risk it. Speaking of cashmere ... I have to share my latest indulgence: cashmere sheets. They are soooo wonderful to sleep on.
