I have a Logiix silicone keyboard protector for my macbook pro. Every couple of months when I take it off, moisture has collected on various keys underneath the silicone. How is this happening? It's not collecting around the edges either, but on the actual letter keys on the middle and such. Any idea where this moisture is coming from? The whole reason I got it is to prevent moisture from potentially getting into the keys, but if the silicone keyboard protector is actually collecting moisture, maybe I shouldn't be using it at all. Thanks if anyone can help.
