How to clean telephone?
use baby wipes or sanitary wipes like the little wet ones you get in a packet at kfc or soemthing you can also buy others at shops make sure to cleamn your mobile phone as well if you have one because those things carry millions of bacteria
depending on how clean try the air duster to get in the number part it works the same stuff they use on key boards or a q tip with water maybe on the last one I've done it and it works but it depends on the phone
It's a very critical task because if you clean telephone system then may be your data will be lost .
Don't use a dishwasher...my phone hasn't worked properly for months :)
unplug it first or youll dial somebody hehe
Just get a dry cloth and whip it.
