Cleaning and maintenance of Sky unit

Hi @WFsupport,

How should we clean the special coating under the sonic transducers?
This is a photo of my Sky #4834 after 52 days outside after some gentle rain:

This is a video squirting water across it trying to clean it:

This is a photo after the squirting:

And after a gentle horizontal shake trying to remove the droplets:

It appears to me that the special coating was either inconsistent or might be wearing off causing the puddle?

I have not touched any of the surfaces inside the gap and this squirt of water is the first time I have tried it.

Wondering what else I can do?
cheers Ian :slight_smile:
