How do you clean usb ports on mac book pro? —– JEFF Comments: 2 Responses to “How to Clean USB Ports On a MacBook Pro?” Gary Rosenzweig 7 years ago I would avoid using any kind of liquid at all. So I would start with a can of compressed air. The type you can get at an office supply store. Blow some compressed air in there and it should take care of any dust or other build-up. Another thing you can do is to use a vacuum. There are some small vacuums used by electronics and computer technicians that will pull dirt and dust out of small places like this. But it may be overboard to try to find something like that if you are not a repair pro. I suppose if there was a big problem — like you dropped the MacBook Pro in mud or something — I would use a small dry brush like a tiny paint brush or electronics cleaning brush. But I would be very gentle and careful. dave 7 years ago Deja Vu all over again. Gary – someone else asked this question a “while” back – you gave the same answer. I agree, if person dropped their MBPro into a mud pile, then take caution and carefully clean out the port with toothpicks, toothbrushes…. If not, and some contacts don’t seem to be working, I’ll post the same answer as then. “QD CRC” Electronic Contact Cleaner available at any auto parts store, WalMart, etc. Red/white and black can. NOT green label for industrial solenoids. Google it.
