The thing is that soapywater has another surface tension than normal water, that COULD be a problem and if that water dries out a litte of that soap could remain maybe on the speaker and sensors! As you see could could could it‘s not that is has to! Once i had a sticky crown on my Series 6 the support recommended to just hold it in a stream of warm tapwater and turn the crown around and even click it several times, worked perfect, so you should not be concerned about showering with it!
