To clean the exterior of a Marshall speaker, you can use a soft, dry cloth to dust off the surface. If the speaker is particularly dirty, you can use a cloth that has been lightly dampened with water. Be sure to wring out the cloth thoroughly to remove any excess moisture, and avoid getting water on the speaker’s controls or connections. If you need to remove stuck-on dirt or grime, you can use a mild, non-abrasive cleaner. Avoid using harsh chemicals, as they may damage the finish on the speaker.
