Take off the sticker on the back of the slider.

 

Um...isn't a tight slider actually desirable for a slider phone? Droid's history would indicate that it gets weaker and more loose with time and even light use.

Keep it tight for as long as possible.

 

This just HAS to be quoted for truth!

 

The other day sprite managed to splatter on my Droid, gumming up the slide mechanism. I simply cleaned off what I could, then applied small dabs of grease in various areas, before sliding it open and closed a few times, letting it get under the panel. I then wiped off any excess that wasn't obviously lubricating, and it's now 100% smooth, sliding better than before the incident occurred.

IMO, the sliding mechanism isn't specialized enough to require any unique brand or safe lube. I just used some stuff that I typically apply on nuts/bolts when working on my cars, and it worked fine. If you don't have anything at home that can lubricate it, try a hardware store or something...they should have something small and cheap that you can apply (provided this is your issue).

 

Only one statement needs be said here:
That's what SHE said!

 

Oh it'll loosen up as time goes on and the more you open it up. Mine was very tight at first, but now it moves in and out with the littlest force.

 

This thread is in danger of drowning in double entendres.
