Wiping off impurities

I am going through a dilemma. The thing is at my work place people eat haram food all the time. I have 2 co workers and the thing is I seen one of my co workers eating haram food and then he touched the phone that we use for our 24/7 work rotation shift. In about a month I will get that same phone. I saw his oily hands touch it after eating the meat taco. Should I wash the phone. Now just today he came to my desk and touched my mouse. Is my mouse considered napaak because with those same oily hands a month back he touched his mouse and all over his desk and then came over and touched my mouse. I figured this is all shaitaan so I just stopped worrying about it and left my mouse. But the phone is kind of putting me off should I wash it? It is a company phone I don't want to ruin it.
