Default The silvery glass strips on all sides of the ZL

I just noticed while cleaning my phone that the top glass panel got some liquid inside it. Asked the local service center if they could remove it by just detaching the glass strip(is it possible?), cleaning the surface, and reattach it again. He said it isn't possible and they'd have to replace the entire housing. T_T couldn't attach pictures yet because I have the only camera phone in the household. It doesn't seem to be affecting the phone performance-wise. I just don't like seeing the liquid 'stain' inside the glass strips.
