I purchased a Martin Fields Overlay Plus for my P800 and it looked really good. Unfortunately, through no one's fault but my own, I managed to put dust/dirt/grime on the adhesive side of the protector. *sigh* The product said it was washable. The guy I got it from said that running water should be just fine... but it still had some marks all over it. I surfed some PDA/Handheld sites and got several suggestions. I tried to do all of the suggested and came up with my own "formula."
Here's what I did:
1. Diluted about 2 drops of dishwashing detergent in a cup of tap water
2. Rinsed the protector by dipping it. Used a sponge to remove the more stubborn dirt (use light strokes and in one direction only!)
3. Placed it on a piece of bond paper (printer paper was recommended but since I couldn't find one in such a short notice I had to make do with regular bond) adhesive side down and let it air dry
4. To clean the P800 screen & the "shiny" side of the protector, I used 3M Scotch-Brite High Performance Cloth
5. Oh-so-carefully place the protector -- adhesive side (dry) down and used the short end of a credit card to remove air bubbles (note: there we still some air bubbles left no matter how much I try to remove them. I decided to keep them that way that go through the hell that I did when I first removed the protector).
6. Resolved to never again remove the protector
In one forum I read it was suggested that (I) use scotch tape to remove lint from the adhesive side but I had problems on that and it almost bent the protector which would be waste of good money!
If anyone has other suggestions I would appreciate it. This is what I did based on other forums and so far, everything seems to be ok. But I'm keeping the protector on until it falls off on it's own.
