When storing your speaker, you should place it in a bag while you're not using it so that it doesn't get dirty or damaged. Damaged speakers can sound much worse than they did before they were damaged since the parts become loose and might rattle inside the casing. The last thing you want is for customers to think your product is defective when really it's just dirty. Once your Bluetooth speaker gets dirty after being stored without a bag, then cleaning with soap and water will help remove any dirt and grime on the outside of the device so it can work like new again.
