Actually if you are willing to disassemble it you can clean it with water. But you must thoroughly dry it afterward. Dab it with a towel to get rid of the water droplets and then aim a fan blowing a large volume of air to finish it. It should be fine afterward. Note that you don’t want to have power to the unit while doing this.... and be sure it is completely dry before powering it up. Of course disassembling a new piece of electronics almost precludes ever getting it back together again, but it is always possible. You could also send it back to the manufacturer and they’ll do it for you.

That said, the less you goof with solid state the better. As long as it works, unless it smells bad I wouldn’t bother...
