Thanks so much for the suggestion to go to the repair guide. My SoundTouch 10 is an off white color. The mesh on my speaker looked very bad, with many stains. I removed the cover quickly, following the instructions. Once I removed the cover, I sprayed it with Windex and scrubbed it with a cotton cloth, making it look as good as new. I rinsed it to remove the soap, then let it dry before replacing the cover. Bose's support team could have been more helpful with what to do. All they told me was that the product was discontinued.
