fingerprints/oil on navi screen.

Also, wipe only horizontally. Has something to do with "grain" of an LCD panel. One of my IT guys told me this for LCD screens on laptops and it does seems to clean better than vertical or circular strokes.

I use Monster iClean. It's for all electronic displays. It's a spray and a special towel. Works amazingly well and doesn't seem to make a difference which way it's applied.

I second the vote for eyeglass cleaner (the type suitable for anti-reflective coatings) and a microfibre cloth. Works fantastic, cheap and is available EVERYWHERE.

I also keep a kit in both vehicles and use it to clean LCD screens (nav and dvd) and the clear plastic for the instrument panels.

We have a specific cleaner for this - it's all I'll use on my NAV screen.

The package comes with the cleaning solution and optex polishing cloth, a kit stays in the glovebox at all times.
