Cleaning inner screen and inner bezel

Hello

I had to open my GCW-Zero due to one of the buttons getting stuck. However. I noticed a few particles of dust on the screen that I wanted to remove (Probably because of no double side tape between the bezel and the LCD). Cleaning it made more particles to show up. I also tried to use sided tape to catch the dust particles. This usually works except for the fact that new particles get in. Also, this one wasn't too good because it left "glue" on the inner bezel and no matter what I try to do to clean it, glue residues are there.

SO my question is more like a generical one for this kind of repair, I have a PSP and a Nintendo 2DS with the screen or bezel replaced and no matter what I do, there's always any kind of residue, be it dust, glue, fingerprints.. even water leaves marks!!

There sure must be a way to leave everything perfect. DO you know it? I hate this kind of repairs because something will always get in no matter what I try. Maybe a solution that cleans the complete screen, leaving it absolutely perfect nd make it repel dust

Right now I am very dissapointed because the screen got worse (button got fixed tho)

Thanks

Thanks

Is it spelled like "ScreenKlin"? I just tried a normal glass cleaner

WHat about hard dirt that's hard to get out such as glue?
