How can I clean a MagSafe power port on my MacBook Air There appears to be a few small metallic fragments clinging to the magnet around the port where the MagSafe power connecter attaches to my MacBook Air. I can still get the cord to (mostly) seat, enough to charge the computer, but it's not as snug a fit as it used to be. How can I clean my MagSafe port?
Start with a pencil eraser or small wooden dowel / tool to gently dislodge the debris. As the magnets are very strong, you may need to use tape with a strong adhesive to grab the foreign material. Clear packing tape strikes a good balance between not leaving residue and getting the crud out. Duct tape also is nice, but a bit more sticky and may grab the plastic covering if it is wearing or the adhesive is warm from internal heat.

So:


Power off the mac
Let the connector cool
Be gentle - don't tear the magsafe covering
know you can get it serviced with a new connector if needed for approx $40 in labor and the part might run you between $10 and $40 depending on the model.


And I know Apple recommends a toothbrush and a cotton swab. The first will get off huge easily removed debris, but not staples and highly magnetic items that are small. The latter is actually quite nice in many cases as it will grab items with a sharp edge. Usually when things are gunked up enough to displace the adapter - you'll have many fine pieces accumulated and need tape or stronger tools than a q-tip.
