I've got a new laptop that I like, but my USB stick has quite some dirt that is sticky and unable to clean, and some dirt which looks like an oxidization or even corrosion. Plugging it into the new laptop USB port, could it be any problems to the laptop
Depends really on the extent and location of the damage. Corrosion around the pins could be rather bad, and could cause short circuiting and malfunction of the device. A bit of dirt is not likely to be as bad, as dirt is less likely to be conductive. Can you post clear photos taken close up in good lighting? – Sir Adelaide – 2016-12-19T05:45:14.253
If you don't already have one, get an external (add-on) hub -- in my part of the world, they are about USD4 in nearly every office or electronics store, supermarket, pharmacy, and gas station, and I wouldn't be surprised to see them at a burger joint -- and use that. If you do damage it, it's much easier and cheaper to replace than repairing your laptop is. – dave_thompson_085 – 2016-12-19T09:02:33.813
