Wash wool/cashmere scarf?

Hello, I needed a warm scarf and found a relatively inexpensive one at ALDI made of 80% wool and 20% cashmere, so I had to jump at the chance. It feels high-quality and is dry-clean only. However, since it has a somewhat "chemical" smell (you have to make some compromises somewhere), I would really like to wash it. How should I wash it, and more importantly, do you also wash "dry-clean only" scarves? Have you had good experiences, or will the scarf then fall apart? It shouldn't fall apart immediately, hopefully not shrink immediately. Since it was quite cheap, I can take a small risk. Thanks for your answers!
