Some solvents will eat plastic. Usually the purer alcohol types are safe for plastics and some contact cleaners would state that on the front of the can.mikefamig said:
Good thought. I have some electronics parts cleaner that I can spray it with. i think that it's a good idea to stay away from the antenna lead with the spray though. My last phone didn't seem to have as good a signal after I sprayed the inside. I thought at the time that the electronic cleaner may have left a conductive residue that affected the antenna signal at the post where the wire connects to the phone. I can't prove it but I think that it's best to leave RF stuff dry.

I think the idea is to soak the solvent into all the small crevices and then drain the liquid out with the dirt and contaminants. What is left is diluted and should dry quickly, maybe on an HVAC register or sunny window with air movement for a day or two.
